Abstract
The influence of the chlorine atom position on the spectral, geometric, and photophysical characteristics of free molecules of dichloroaniline is studied by electron spectroscopy, fluorescence, and quantum chemistry. A chlorine atom included in the aniline aromatic ring is shown to exhibit properties inherent in a heavy atom, that is, the radiation is dominated by phosphorescence. According to quantum-chemical calculations, the quenching of fluorescence is due to the fact that the efficiency of the intersystem crossing conversion proves to be much higher than the radiative decay rate of the S1 state.
