Time Resolved Two‐Color Multiphoton Ionization Studies on the Intramolecular Dynamics of Cycloheptatrienes

Abstract
One and two color multiphotonionization experiments in cycloheptatriene, methyl‐, ethyl‐, and isopropyl‐cycloheptatriene are reported. Rate constants for the fast internal conversions S1 → S0 of these molecules were determined. A collisional deactivation process in the pathway of time delayed two color multiphoton ionization is observed.
