Inner-shell excitation of PF3, PCl3, PCl2CF3, OPF3 and SPF3 Part I. Spectroscopy

Total ion yield spectra of PF3, PCl3, PCl2CF3, OPF3 and SPF3 were recorded in the region of P 2p, P 2s, S 2p, S 2s and halogen (Cl 2p, F 1s) excitation using synchrotron radiation. The P 2p spectra are interpreted with GSCF3 ab initio configuration interaction calculations optimized for core excitation studies. The experimental–theoretical comparison is based on both absolute intensities (oscillator strengths) and transition energies. The …
