THE SEARCH FOR CHARGE TRANSFER STATES: BENZONITRILE AND RELATED MOLECULES

Abstract

The high resolution electronic spectra of benzonitrile and related molecules have been recorded, including several higher vibronic bands in the $S_{1} \leftarrow S_{0}$ system. Analyses of the spectra provide information about the geometries of the different molecular assemblies in both their ground and first excited states. There is no evidence for a charge transfer state up to $+703 cm^{-1}$ above the $S_{1}$ origin transition. Related molecular assemblies will also be discussed.
