Abstract

We report a femtosecond time-resolved photoelectron spectroscopy (TRPES) investigation of internal conversion in the first two excited singlet electronic states of styrene. We find that radiationless decay through an S1/S0 conical intersection occurs on a timescale of 4 ps following direct excitation to S1 with 0.6 eV excess energy, but that the same process is significantly slower (20 ps) if it follows internal conversion from S2 to S1 after excitation to S2 with 0.3 eV excess energy (0.9 eV excess energy in S1).
