Abstract

Resonance Raman spectroscopy under conditions of resonance with the B1u state of benzene exhibits strong binary overtone activity due to the vibronic activity of the e2g vibrations, especially νg. Resonance with the analogous La state of benzene derivatives exhibits activity in both the fundamental and two-quantum overtone of this mode in a fashion that reflects the relative amounts of vibronic and substituent induced allowed character of the electronic transition. The Raman spectra can be used to test simple perturbative ideas concerning inductive effects originally proposed by Petruska. In this work we describe recent theoretical and experimental studies of such effects. The theory includes the Jahn-Teller and pseudo-Jahn-Teller effects in a non-perturbative fashion. The experiments are aimed at determining what happens when the interaction of the substituent with the benzene π-electron system is strong so that perturbative arguments are no longer expected to apply.
