Picosecond pump-probe multiphoton ionization and zero electron kinetic energy (ZEKE) photoelectron spectroscopy are applied to study five vibronic bands in the S-1 state of benzene. The goal is to measure the nonradiative decay processes in the channel three region including both overall electronic state relaxation which leads to a loss of S-1 population and intramolecular vibrational redistribution (IVR) which is due to vibronic coupling within the S1 state. The lowest energy band studied, 6(1)1(2) at 2367 cm(-1), is below the channel three region while the other four bands, 6(1)1(3), 7(1), 7(1)1(1), and 6(1)1(4), are considered to be near or above the channel three threshold. The measurements of overall electronic state decay agree with the previous determinations by Sumitani et al. The picosecond ZEKE experiments reveal that the 7(1) and 7(1)1(1) bands show little or no evidence for IVR on the time scale of the electronic state decay (>100 ps) while the 6(1)1(3) band apparently undergoes rapid IVR with a time constant of similar to 35 ps. The results are compared with some of the recent studies on benzene, including the picosecond fluorescence results of Sumitani er al., the chemical timing experiments of Longfellow et al., and the rotationally resolved spectral and dynamics studies of Riedle el al.
