Abstract

The fluorescence/phosphorescence excitation spectra, the dispersed fluorescence/phosphorescence spectra and the sensitized phosphorescence excitation spectrum have been measured for jet-cooled p-benzoquinone. The assignments of vibronic bands in the ¹B_1g(n_-,π∗) ← ¹A_g and ¹A_u(n₊,π∗) ← ¹A_g transitions have been definitely established. The phosphorescence spectra from vibronic levels of ³A_u exhibit a feature of single vibronic level emission. The ³A_u ← ¹A_g transition was also vibrationally analyzed.
