Untangling π-π~*-π~* Orbital Interactions Via Ultrafast Time-Resolved Photoelectron Spectroscopy

摘要

The ultrafast photochemical dynamics of π-π~*-π~* orbital interactions are determined using time-resolved photoelectron spectroscopy. We compare the spectra of several linear α,β- enones and 1,3-butadiene. We find two different ultrafast decay paths for the α,β-enones, both predicted by ab initio calculations.
