โฆ Synopsis
The vibronk interactions involved in the phosPhorescent triPlet state of p-chlorg&niline m p-x$ene have been studied by the method of microwave induced delayed phosphores~nce. It is shown that vibrations of bi symmetry : appear strongly in the emission from the Tr sublevel. l%is unusual appearance of a bz mode is.discusxd in some detail and the pseud*J&n-Teller distortion is suEested as a possible explanation.

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
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
