The absorption spectrum of p-benzoquinone has been studied at 20 K. in the crystalline state from 15000 to 35000 cm.-1, using single crystals in polarized light. It is concluded that there are at least three distinct-* transitions between 18000 and 25000 cm.'1, as well as a-* transition near 30000 cm.-1. The-* transitions are very sharp, and partial vibrational analyses are presented. The ir-* transition is much more diffuse and shows evidence of predissociation in the excited electronic state. The spectra are classified with respect to theoretical calculations and semi-empirical correlations. No fluorescence or phosphorescence was observed. The spectra are compared in detail with the vapor and solution spectra obtainedby previous workers.
