Excited States And Photochemistry Of Saturated Molecules. Vii. Potential Energy Surfaces In Excited Singlet States Of Methane, Mark S. Gordon, James W. Caldwell Jan 1979

Excited States And Photochemistry Of Saturated Molecules. Vii. Potential Energy Surfaces In Excited Singlet States Of Methane, Mark S. Gordon, James W. Caldwell

Mark S. Gordon

Potential energy surfaces are investigated for a number of low‐lying excited singlet states of methane, using a split valence plus Rydberg basis set and singly excited CI. Of the six minima found, the lowest two are valence states. The lowest minimum corresponds to the products 1 1 B 1 CH2+1 1Σ g + H2, in agreement with the observed threshold photochemistry, and is accessible by five separate routes from the lowest vertical state. The second valence minimum is a square planar structure. Of the four Rydberg minima detected, one is a local minimum on the otherwise dissociative B 1surface and …

Gas Phase Laser Induced Fluorescence Spectroscopy Of Cfcl, Stephen E. Bialkowski, David S. King, John C. Stephenson Jan 1979

Gas Phase Laser Induced Fluorescence Spectroscopy Of Cfcl, Stephen E. Bialkowski, David S. King, John C. Stephenson

Stephen E. Bialkowski

The CFCl radical has been produced in the gas phase by both IR multiphotonphotolysis of C2F3Cl and He metastable reaction with C2F3Cl. Single vibronic level fluorescence and excitation spectra taken of this species have yielded sufficient information to determine certain vibronic constants. The excited state was found to have an origin of T0=25 283±5 cm−1 with vibrational frequencies: ω2′=394±3 cm−1 and ω3′=739±5 cm−1. In the ground state, the vibrational frequencies were found to be: ω3″=118±10 cm−1, ω2″=448±6 cm …
