Photoinduced molecular chirality probed by ultrafast resonant X-ray spectroscopy
arXiv:1612.06909 · doi:10.1063/1.4974260
Abstract
Recently developed circularly polarized X-ray light sources can probe ultrafast chiral electronic and nuclear dynamics through spatially localized resonant core transitions. We present simulations of time-resolved circular dichroism (TRCD) signals given by the difference of left and right circularly polarized X-ray probe transmission following an excitation by a circularly polarized optical pump with variable time delay. Application is made to formamide which is achiral in the ground state and assumes two chiral geometries upon optical excitation to the first valence excited state. Probes resonant with various K-edges (C, N and O) provide different local windows onto the parity breaking geometry change thus revealing enantiomer asymmetry.
