Abstract
Abstract Absorption and fluorescence spectra of 2-phenylbenzimidazole has indicated that the geometry of the molecule is the same in S0 and S1 electronic states. The fluorescence takes place from the Lb electronic state. Excited-state equilibrium constants have been calculated for PBI+ ⇌ PBI ⇌ PBI− equilibria.
