Molecular Field effects investigated by Polarized Resonant Inelastic X-ray Scattering
POSTER
Abstract
Angular dependence of the Cl 2p spin-orbit components is observed experimentally in resonant inelastic x-ray scattering (RIXS) after 1s excitation in CF$_3$Cl and HCl. Theoretical analysis interprets this dependence by population differences in the 2p$_{x,y,z}$ states, and molecular-field and singlet-triplet exchange effects. Thus, polarized RIXS provides a direct measurement of the 2p$_{x,y,z}$ states populations, and a probe of the molecular environment.
