Abstract:Channel
competition and further photochemical control of relaxation
pathways in excited molecules are of primary importance in photochemistry
and related areas. Acrolein, as the simplest and most typical α,β-enone, is suitable to provide a model for
understanding the photochemistry and photophysics of α,β-enones. Here, the ultrafast dynamics in acrolein following S1(nπ*) excitation has been studied by time-resolved photoelectron
imaging (TRPEI) and mass spectroscopy. The competition between intersystem
crossi… Show more
