The Purely Electronic Transition Frequency from Magnetically Induced Diffuse Vibronic Spectra
Abstract
It is shown that the average distance between the combining electronic states, including ones under magnetically induced circular luminescence, is determined from the diffuse electron-vibrational (vibronic) absorption and emission spectra of the magnetically induced optical activity (MOA) at the thermal equilibrium of the initial states in the transition. It differs significantly from the average distance between the vibronic states combining in the transitions. The difference in the transition mechanisms is reflected in the difference not only in the spectra, but also in the purely electronic transitions of the MOA. The heterogeneity of the ensembles of MOA molecular chromophores is qualitatively manifested in the MOA spectra by the blurring of the indication of a purely electronic transition.
