Abstract
The effect of the position and number of chlorine atoms on spectral, geometrical, and photophysical characteristics of individual molecules of chlorine-substituted derivatives of aniline is studied by electronic spectroscopy and quantum-chemical calculations. It is shown that the long-wavelength absorption band of these compounds is formed by several electronic transitions of different nature and intensity. It is ascertained that electronically excited π σ* states involve C-Cl bonds, which weaken upon excitation. According to quantumchemical calculations, the quenching of fluorescence of chlorine-substituted derivatives of aniline is determined by the fact that intersystem crossing is more effective than radiative decay of the S 1 state.
