SPLITTING OF DEGENERACY OF THE BENZENE: RADICAL CATION GROUND STATE BY ASYMMETRIC SUBSTITUTIONS

Abstract

Various Substituted benzene cations were studied by time, wavelength, and polarization resolved laser induced flourescence in solid No matrices. The polarization behaviour identifies unambiguously emission bands belonging to the $B\rightarrow A$ electronic transition. The ground state vibrational structure and vibronic interactions with the low lying A state are examined.
