Electronic decay of core-excited HCl molecules probed by THz streaking

Structural Dynamics, 2019
The ultrafast electronic decay of HCl molecules in the time domain after resonant core excitation was measured. Here, a Cl-2p core electron was promoted to the antibonding σ* orbital initiating molecular dissociation, and simultaneously, the electronic ...
