The 700-1500 cm-1 region of the S1 (A 1B2) state of toluene studied with resonance-enhanced multiphoton ionization ( REMPI), zero-kinetic-energy (ZEKE) spectroscopy, and time-resolved slow-electron velocity-map imaging (tr-SEVI) spectroscopy

We report (nanosecond) resonance-enhanced multiphoton ionization (REMPI), (nanosecond) zero-kinetic-energy (ZEKE) and (picosecond) time-resolved slow-electron velocity map imaging (trSEVI) spectra of fully hydrogenated toluene (Tol-h(8)) and the deuterated-methyl group isotopologue (alpha(3)- Tol- d(3)). Vibrational assignments are made making use of the activity observed in the ZEKE and tr-SEVI spectra, together with the results from quantum chemical and previous experimental results. Here, we examine the 700-1500 cm (1) region of the REMPI spectrum, extending our previous work on the region less than or similar to 700 cm(-1). We provide assignments for the majority of the S-1 and cation bands observed, and in particular we gain insight regarding a number of regions where vibrations are coupled via Fermi resonance. We also gain insight into intramolecular vibrational redistribution in this molecule. (c) 2014 AIP Publishing LLC.
