ANALYSIS OF (D)OVER-TILDE2A1-(C)OVER-TILDE2T2 EMISSION BANDS OF CF4+ UNDER HIGH-RESOLUTION

High-resolution emission spectra of D 2A1-2T2 transitions in CF4+ were obtained from a hollow cathode discharge in CF4/He mixtures. The partly resolved rotational structures of the 0-0, 1(2)0 and 1(2)0 bands were analysed on the basis of a model Hamiltonian developed by Watson for tetrahedral molecules. Spectroscopic constants were determined via computer simulations and relations for intervals between heads of branches. Spin-orbit coupling, Coriolis interaction and Jahn-Teller distortion in the lower electronic state were found to be relatively small but to show a vibrational dependence on v1.
