Description
Summary:A detailed spectroscopic analysis of the electronic absorption spectrum of the perylene radical cation, produced in a boric acid film by photo-oxidation is reported. To interpret the experimental spectrum, the electronic energy levels and oscillator strengths have been calculated using the Pariser—Parr molecular orbital method with limited configuration interaction. The effect of variation of solute concentration and irradiation time of the films has also been studied. It is found that the agreement between experimental and theoretical results in excellent.
