It is shown that the microwave induced delayed phosphorescence technique can be developed into a very general method. It is possible to measure not only decay rates of the individual spin components of ohosohorescent triplet states as shown in a previous paper. but also the relative radiative decay

โฆ Synopsis
Using microwave induced delayed phosphorescence techniques we determined the populating and depopulating rate txnshnts for the indivldnat spin-sublevels of tile phosphorescent states of tetracyanobenzene (TCNB) and its ebargetransfer complexes with besrene and hesamethyibenzene (H&13) in n-hexane at 1.25 K. It was shown that tbe nonradiative decay process frcm the short& lifetime sublevel is most responsible for the previously observed shortening in the phosphorescence !ifetime of the TCNB-HMB complex.

The zero-field splitting parameters of the lowest triplet state of toluene in a benzene crystal have been measured: D = 0.146, IEI = 0.0463 cm-l. The relative contributions of the three spin levels to the radiative decay in four vibronic bands have been determined. The results indicate that the axes
