Real-time structural dynamics of the ultrafast solvation process around photo-excited aqueous halides.

ABSTRACT: This work investigates and describes the structural dynamics taking place following charge-transfer-to-solvent photo-abstraction of electrons from I^- and Br^- ions in aqueous solution following single- and 2-photon excitation at 202 nm and 400 nm, respectively. A Time-Resolved X-ray Solution Scattering (TR-XSS) approach with direct sensitivity to the structure of the surrounding solvent as the water molecules adopt a new equilibrium configuration following the electron-abstraction process is utilized to investigate the structural dynamics of solvent shell expansion and restructuring in real-time. The structural sensitivity of the scattering data enables a quantitative evaluation of competing models for the interaction between the nascent neutral species and surrounding
