Second Row Molecular Orbital Calculations. Geometries, Internal Rotation Barriers, And Dipole Moments Of Methylsilane, Disilane, Methyl Mercaptan, And Methyl Phosphine, Mark S. Gordon, Loren Neubauer Sep 1974

Second Row Molecular Orbital Calculations. Geometries, Internal Rotation Barriers, And Dipole Moments Of Methylsilane, Disilane, Methyl Mercaptan, And Methyl Phosphine, Mark S. Gordon, Loren Neubauer

Mark S. Gordon

The internal rotation barriers of methylsilane, methyl mercaptan, methylphosphine, and disilane are calculated with and without complete geometry optimization in three different CNDO parametrizations. It is found that Santry's recent reparametrization is most reliable for both geometries and barriers and that geminal and bonded interference interactions are more important than those between vicinal atoms for these molecules. None of the parametrizations give reasonable dipole moments.

Observation Of Persistent Currents In A Saturated Superfluid Film, Robert Hallock, R. K. Galkiewicz Jan 1974

Observation Of Persistent Currents In A Saturated Superfluid Film, Robert Hallock, R. K. Galkiewicz

Robert Hallock

We report the first observation of a persistent flow around a closed path consisting entirely of saturated superfluid helium film in a macroscopic geometry in which the saturated vapor was in unconstrained proximity to the film

Quasi-Isothermal Superfluid Film Oscillations, Robert Hallock Jan 1974

Quasi-Isothermal Superfluid Film Oscillations, Robert Hallock

Robert Hallock

We have carried out a detailed study of the frequency and damping of the oscillations in levels of two reservoirs of HeII which are coupled only via the mobile superfluid film. Our experiments cover the temperature range 1.2
