摘要: The emission spectra of C6F6 +, C6F5H+, the three C6F4H2 + and two C6F3H3 (1, 2, 4 1, 3, 5) cations were obtained in gas phase, a special discharge tube. Symmetry mode correlation fundamental frequencies parent neutral molecules enabled isodynamic molecule method to be used for achieving vibrational analysis ion spectra. vibronic structure each spectrum is interpreted. Dynamic Jahn-Teller effects are shown occur degenerate ground state 5-C6F3H3 particular irregular ground-state progressions 6 observed. Extensive calculations made +; intensities its good agreement with results based on linear coupling model Longuet-Higgins et al., using deperturbed frequency ω = 477–484 cm-1 dimensionless interaction parameter D 0·13-0·10. A review data photoelectron Rydbe...
