Fig. 2: Absorption spectrum and XCD signal.
From: Element- and enantiomer-selective visualization of molecular motion in real-time
a Steady-state carbon K-edge absorption spectrum of S-IBP recorded with circularly left (blue trace) and right (red trace) polarized light. The sticks represent the calculated transition energies and oscillatory strengths for the first core-excited state of each of the 13 carbon atoms in the molecule. Black sticks are the transitions investigated in the present work. b Steady-state carbon K-edge X-ray circular dichroism (XCD) signal calculated as the difference of the L and R spectra shown in panel a, normalized by their sum. Insets in panel b show the selected atoms by the corresponding probe wavelength and their numbering. Numbers in brackets refer to the S enantiomer.
