Ours and literature data on influence of replacement of deuterium by protium in complex organic molecules on nonradiative triplet-singlet transition rates are discussed from the standpoint of the inductive-resonant theory of this process. It has been shown that the extent to which the protium introduction in molecule affects the nonradiative rate depends on distance between protium atom and the vibronic molecular oscillator of triplet-singlet transition and on π -electronic density near-by protium.
