Abstract
We report on the UV-induced photochemistry of the biologically relevant sulfur-containing thiol group and the disulfide bond in solution using picosecond X-ray absorption spectroscopy at the sulfur K-edge. This study provides element-specific insight into the 267-nm induced photo-chemistry of two model compounds, an aromatic thiol and an aliphatic disulfide. Our transient spectra point to two primary and several secondary photoproducts, and our analysis may aid in understanding UV damage in proteins.
