The decay of sensitizer phosphorescence in a rigid solution modified by the electronic energy transfer by the mechanism of dipole‐dipole interaction mixing with the dipole‐quadrupole interaction is proposed. The rate constant for the transfer process transfer process as (equation).where (equation). Calculations are made of the yield and the decay time of the sensitizer phosphorescence as functions of the activator concentration and the mixing coefficient of dipole‐dipole interaction with dipole‐quadrupole interaction. It is hoped that the proposed mechanism will provide a sound, quantitative basis for analyzing experimental data in a triplet‐singlet energy transfer process. As a demonstration, results indicate that about 9% of the electronic energy radiationlessly transferred from triplet triphenylene‐d 12 to singlet Rhodamine B is induced by the electric dipole‐quadrupole coulombic interaction.
