Theoretical Analysis Of The Vibrations And Rotations Of The B¹[Sigma][Mu] State Of The Hydrogen Molecule, Sandra Zink Moody

Physics & Astronomy ETDs

Theoretical calculations of the rotational-vibrational constants of the B¹Σ⁺_u state of H₂ were made using the Dunham analysis and by fitting equations to energy eigenvalues. The potential energy function for the nuclei used in the calculations was computed by W. Kolos and L. Wolniewicz using the variational technique. The power series used in the Dunham analysis made use of Stirling's central difference interpolation polynomial. The equilibrium separation R_e found from the Born-Oppenheimer potential is 2. 42916₅ atomic units, differing from the Kolos-Wolniewicz value of 2.4288. Adiabatic corrections were taken into account through a …

Stratigraphy And Structure Of The Northwestern Guadalupe Mountains, New Mexico, Klyne Headley

Earth and Planetary Sciences ETDs

The northwestern Guadalupe Mountains of southeastern New Mexico are part of a large regional cuesta that slopes gently northeast. The crest of the northern escarpment rises abruptly to more than 2,200 feet above Pinon Valley.

The rugged west-facing escarpment has been carved in an uplifted fault block composed entirely of Permian sedimentary rocks having an aggregate thickness of about 1,700 feet. Dark-red to buff siltstone, gray dolomite, and white to gray gypsum compose the Yeso Formation. Conformably overlying these rocks is the dark-brown limestone and dolomite sequence of the San Andres Formation. The Glorieta Sandstone which usually occurs between these …

Response Prediction For The Oso-G Satellite Solar Neutron Instrument By Matrix Methods., John Coalmer Conklin

Physics & Astronomy ETDs

Properties of the University of New Mexico’s solar neutron instrument for use on the NASA 0S0-C satellite were investigated. A sensor model was developed by use of two computer codes. First, the total efficiency of the converters was calculated by a simulation code with a resulting total efficiency at 100 Mev of approximately two per cent of which four-fifths was carbon recoil contribution.

Second, geometry properties of the instrument were provided by a Monte Carlo program, with maximum geometry efficiency equaling about fourteen per cent. These were combined to give a total response profile for the instrument which was expressed …

The Motion Of A Charged Particle In The Field Of A Magnetic Dipole, E. Royce Fletcher

Physics & Astronomy ETDs

The principal difficulties encountered in attempting to solve the general problem of the motion of a non-relativistic, non-radiating charged particle in a magnetic field which varies position and time, are associated with the induced electric field. That is to say, the time variation of the magnetic field produces an electric field which also acts on the particle. Both these fields must be known as functions of time and position if the equations of motion are to be determined exactly.

The Spectroscopic Constants Of The Ground Electronic State Of Hydrogen Molecular Ion, Bertle Daniel Hansen

Physics & Astronomy ETDs

ABSTRACT

An accurate theoretical determination of certain vibration rotation properties of the hydrogen molecular ion is made. Two different methods of analysis are used in the determination of these properties. First, an energy equation for diatomic molecules is

fitted directly to theoretical vibration and rotation eigenenergies of the ground electronic state of H+2 calculated by J.M. Peek. These eigenenergies include adiabatic corrections determined by w.Kolos. Second, a fixed-nucleus potential for the ground electronic state of H+2, calculated by J. M. Peek which did not include adiabatic corrections, is expanded in a power series in the neighborhood of the equilibrium internuclear …

Petrography And Structure Of The Pedernal Hills, Torrance County, New Mexico, Ralph Alan Gonzales

In the Pedernal Hills, in the eastern part of north-central New Mexico, five Precambrian metamorphic and igneous rock types occur. Stratigraphically, oldest to youngest, they include medium-grained granite gneiss; quartzite, quartz-mica schist, and quartz-specular hematite schist; schist unit consisting mainly of quartz-muscovite schist and greenstone; intrusive granite which includes rocks ranging from quartz diorite to alkali granite; and cataclasite representing dynamically metamorphosed rocks.

The Synthesis Of 5- And 8-Dialhylamino-Alkylaminopyrido [2,3-D] Pyridazines As Potential Antimalarial Agents., William M. Rich

Chemistry and Chemical Biology ETDs

The appearance of strains of malaria resistant to most of the synthetic antimalarial agents has prompted the investigation of new compounds for antimalarial activity. The structural similarities of the nucleus of pyrido [2,3-d] pyridazine to pteridine as well as to the known quinoline antimalarials suggested the possibility of development of potential chemotherapeutic agents based on the ring system.

A series of 5,8 substituted pyrido [2,3-d] pyridazines were prepared in which one substituent was a dialkylaminoalkylamino group and the other substituent either a chloro, ethoxy, or hydroxy group. Ultraviolet, infrared, and nuclear magnetic resonance spectra were reported for all compounds. Structures …

The Geology Of The Jicarilla Mountains, Lincoln County, New Mexico., George Ernest Ryberg

Earth and Planetary Sciences ETDs

The Jicarilla Mountains in west-central Lincoln County, New Mexico, consist of Permian, Triassic, and Cretaceous sediments intruded by Tertiary sills, dikes, laccoliths, and stocks. The upper 50 feet of the Yeso Formation is exposed and is conformably overlain by the San Andres Formation which consists of the lower Sandstone, and middle Limestone, and upper Gypsum members. The Permian Artesia Formation, which is about 300 feet thick, unconformably overlies the Gypsum member. Unconformably overlying the Artesia Formation is a 200-foot section of the Triassic Santa Rosa Formation. The boundary between the Santa Rosa Formation and the overlying Chinle Formation is gradational. …

Pressure And Temperature Dependence Of The Acoustic Velocities In Polymethylmethacrylate, James Russell Asay

Physics & Astronomy ETDs

The acoustic velocities in polymethylmethacrylate have been measured with an ultrasonic pulse echo technique as functions of frequency, temperature and pressure. At atmospheric pressure, data on the velocities and attenuation coefficients were obtained over the range of temperature from 22°c to 75°c and for the frequency range of 6 to 30 MHz. At the temperatures of 25, 40, 55 and 75°c, the pressure dependence of the longitudinal and shear velocity was obtained to 150,000 psi at a frequency of 6 MHz. From the frequency measurements of the velocities, the complex elastic moduli in polyrnethylmethacrylate were calculated at room temperature. The …

Dose And Depth Dose Measurements On The Sixth Gemini Flight, A Comparison With The Gemini-4 Radiation Measurements, Marion F. Schneider

Physics & Astronomy ETDs

Two tissue-equivalent ionization chambers were flown behind 0.4 gram/cm.² and 2.5 grams/cm.² of shielding inside the Gemini-6 spacecraft. The instruments measured the radiation levels resulting from primary cosmic radiation and the trapped particle environment of the earth's Van Allen belts. Each sensor was constructed from a special tissue-equivalent plastic with radiation cross sections that closely match standard muscle tissue for the many complex types and energies of radiation encountered in space. The design of the sensor and logarithmic electrometer preamplifier are described in detail. The calibration and directional sensitivity of the sensors with cobalt-60 and cesium-137 gamma radiation …

Geology Of The Southern Pilot Range, Elko County, Nevada And Box Elder And Tooele Counties, Utah, John Michael O'Neill

Earth and Planetary Sciences ETDs

The southern Pilot Range is a slightly sinuous, north-trending mountain range located in the northeastern part of the Great Basin.

Approximately 18,500 feet of miogcosynclinal sedimentary rocks representing every system from late Precam­brian to Permian(?) are exposed in the southern Pilot Range. Because of intense faulting, many of the strati­graphic relationships between the formations are impossible to determine. Mesozoic and Tertiary strata are absent; however, Pleistocene Lake Bonneville deposits are wide­ spread, although thinly distributed. Small igneous stocks, dikes, and sills are common only in the southern two-thirds of the map area. Stocks are principally granodioritic. In several cases the …

The Approximate Scf Lcao-Mo With Cndo Theory And Electronic Structures Of N-Heterocyclic Benzene Analogues, Jay Jea-Yong Rhee

Chemistry and Chemical Biology ETDs

The approximate MO theory in this study expIicitly refers to the Pople molecular orbitaI treatment. This consists of complete neglect of differential overlap (CNOO) in the self-consistent field treatment of the molecular orbitals, analogous to the Hartree-Fock treatment of atomic systems, which are constructed as Iinear combinations of atomic orbitals (LCAO). Furthermore, the only orbital functions considered in a basis set are those for the valence electrons and the atomic orbitals are Slater-type orbitals. The major investigation of this study is to apply this approximate MO theory to the series of nitrogen heterocyclic benzene analogues. The quantities that have been …

The Red Leak And Its Effect In Ultraviolet Photometry., Jeffrey David Colvin

Physics & Astronomy ETDs

The red leak in the red 􀀉and of the ultraviolet filter (Corning #9863) of the standard UBV photometric system is investigated. Astronomical photometry is discussed in general, and UBV photometry in particular. The photometric system used in this work is also discussed, including telescope, phototube, filters, and amplifier. The standard filters of the UBV system are used, but the standard phototube of this system is not used. An analytic representation of the red leak magnitude correction is developed.

Sixty-five measurements were made for a wide variety of stars from spectral class B3 to spectral class M2. The red leak correction …
