Determining the Frequency of a Purely Electronic Transition from Optical Activity Spectra

  • Published:
Journal of Applied Spectroscopy Aims and scope

The possibility of determining the frequency of a purely electronic transition from circular dichroism, circularly polarized luminescence, and magnetically induced optical activity spectra and the spectral dependence of the coefficients of circular dichroism dissymmetry is demonstrated. Examples of such determination from experimentally measured molecular optical rotation spectra in absorption and emission are presented. It was shown that the frequency of a purely electronic transition in the spectral dependences of the dissymmetry coefficients can be indicated by an extremum. As in diffuse linear vibrionic spectra, the frequencies of the purely electronic spectra do not correspond to maxima in the spectra.
