Abstract

Resonance Raman scattering spectra have been obtained for the electrogenerated monoanion radical of tetracyanoquinodimethane (TCNQ) upon excitation of its lowest 2B1u excited state with Ar+, Kr+, and Ar+ pumped CW dye lasers. In addition we report the preresonance Raman spectrum of neutral TCNQ excited with the 4579 Å Ar+ laser line. The utility of resonance Raman spectroscopy as a molecularly specific monitor for electrochemical processes is discussed along with an interpretation of the measured frequency shifts between TCNQ and TCNQ·- based on the bond order changes determined from SCF-LCAO-MO calculations.
