We report results from a recent laser pump–probe study into the ultrafast ring-opening dynamics of 1,2-dithiane. Following absorption of a 290 nm photon, the nuclear dynamics were probed as a function of pump–probe delay on the femtosecond timescale by strong-field ionisation with an 800 nm probe pulse, resulting in production of a range of atomic and molecular fragment ions…

Disulfide bonds are ubiquitous molecular motifs that influence the tertiary structure and biological functions of many proteins. Yet, it is well known that the disulfide bond is photolabile when exposed to ultraviolet C (UVC) radiation…

Monitoring the Evolution of Relative Product Populations at Early Times during a Photochemical Reaction
Identifying multiple rival reaction products and transient species formed during ultrafast photochemical reactions and determining their time-evolving relative populations are key steps toward understanding and predicting photochemical outcomes. Yet, most contemporary ultrafast studies struggle with clearly identifying and quantifying competing molecular structures/species among the emerging reaction products…
