The technique of time-resolved ESR together with the photosensitization method was applied to obtain information on the triplet lifetimes and spin-depolarization rates of some model bromo-substituted naphthalene compounds. In the triplet excitation transfer process at high field the magnetic quantum

Data on the rate of triplet-triplet energy transfer to stilbenes are reinterpreted in terms of the overlap of the TI H So transition bands in the sensitizer and acceptor. So-called 'non-vertical" excitation follows closely the Franck-Condon probabilities in the spectra, the "phantom triplet" being i
Time-resolved resonance Raman spectra of the first triplet state of biphenyl derivatives are reported in the range 300-1800 cm-'. Convincing assignments and satisfactory correlation with the ground-state assignments are proposed. The DZh planar quinoidal character of T, biphenyl is shown by various
The triplet-triplet energy-transfer process from xanthone to naphthalene was studied in a r-cyclodextrin system at 77 K using a time-resolved ESR method. The efficient inclusion of these two molecules and the formation of a fixed configuration between them in a y-cyclodextrin cavity were found with
## Photolyses of solutions of various quinones in the presence of organotm and organokad mmpounds yield paramagnetic organometal adducts of the qumones. Time-resolved CIDEP observations indicate that the organometals having relatively low lomzation potentials quench the carbonyl tnplet wa a charge
