Ultrafast electronic relaxation pathways of the molecular photoswitch quadricyclane

Using time-resolved photoelectron spectroscopy (TRPES) along with non-adiabatic molecular dynamics simulations we have succeeded in tracking the two competing pathways by which electronically excited quadricyclane molecules relax to the electronic ground state. K.D.

Quadricyclane and norbornadiene are two isomers that interconvert upon absorption of ultraviolet light. In the present study, we use time-resolved photoelectron spectroscopy (TRPES) with extreme ultraviolet (XUV) probe pulses, capable of tracking the entire reaction path from the initial UV-excited states through to the electronic ground states of both isomers.
