Abstract

High-resolution electron yield spectra of CH4, CH3F, CH2F2, CHF3, and CF4 are observed in the vicinity of C 1s and F 1s thresholds and interpreted with the help of ab initio SCF calculations. Resonance spectator and participant Auger spectra are observed following the C 1s and F 1s excitations of these molecules and discussed in terms of the characters of the orbitals of the electrons involved in the electronic decay. The electronic decay from the fragments is also observed for CH2F2, CHF3, and CF4 at the C 1s → σz.ast; C-F antibonding excitation.
