Core-hole localization and ultra-fast dissociation in SF6
(2020) In Journal of Physics B: Atomic, Molecular and Optical Physics 53(18).- Abstract
Resonant inelastic x-ray scattering spectra excited at the fluorine K resonances of SF6 have been recorded. While a small but significant propensity for electronically parity-allowed transitions is found, the observation of parity-forbidden electronic transitions is attributed to vibronic coupling that breaks the global inversion symmetry of the electronic wavefunction and localizes the core hole. The dependence of the scattering cross section on the polarization of the incident radiation and the scattering angle is interpreted in terms of local π/σ symmetry around the S-F bond. This symmetry selectivity prevails during the dissociation that occurs during the scattering process.
