The research carried out covered a number of research areas. The use of spins of the lowest triplet state was studied as a probe of intramolecular intersystem energy transfer in molecules. The interplay between singlet and triplet of different electronic nature was quantitatively examined publications 1-5, 8 and 13. Nonradiative processes in the gas phase and in solution were studied in publications 7,10,11 and 14. Spectral diffusion studies due to intermolecular energy transfer in solids were made for both spin transitions publications 15 and 16, electronic transitions of rare earth ions in glasses publications 6,17,18 and 20 and singlet-triplet electronic transitions in orientationally disordered solids publications 19, 21-23. In all these studies, the mechanisms of the energy transfer processes involved are investigated in terms of the interaction coupling involved.
