Query: Photoinduced molecular chirality probed by ultrafast resonant X-ray
  spectroscopy   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.
