Unpicking vibration-vibration and vibration-torsion interactions in m-fluorotoluene

Davies, Alexander R.; Kemp, David J.; Wright, Timothy G.

Abstract

Two-dimensional laser-induced fluorescence (2D-LIF) spectra are reported for a set of features in the S1 ↔ S0 electronic spectrum of m-fluorotoluene. Two transitions previously assigned to fundamentals are reassigned in the present work. The main reassignments are confirmed with zero-electron-kinetic-energy (ZEKE) spectroscopy. Interactions in the S0, S1 and D0+ electronic states involving vibrational and vibration-torsional (“vibtor”) levels are identified via observed activity. The obtained vibrational wavenumbers compare well to the results of quantum chemical calculations.
