Thiophenone
WebThe photoinduced ring-opening and subsequent rearrangement reactions of isolated 2(5H)-thiophenone were studied based on geometry optimizations on critical structures and nonadiabatic dynamics simulations using this method. Upon 267 nm irradiation, the molecule is initially populated in the 1 ππ* state. After a sudden rupture of one C–S ... WebJul 20, 2024 · The potential energy acquired by thiophenone upon photoexcitation is converted, in part, to nuclear kinetic energy during the non-radiative decay to the S 0 state, but these are closed systems:...
