Optically detected magnetic resonance (ODMR) techniques are used to determine the orbital asQnment of the phosphorescent triplet state of p-benzoquinone in the condensed phase. The principal spin-orbit coupl% routes are discussed in terms of the observed spin-vibronic activity.

β¦ Synopsis
We have measured the temperature dependence of the spin coherence and the resonance frequencies of a triplet state under the influence of vlbronic relaxation. We derive the hfetime and zero-field splitting parameters of the excited vibromc level.

## Rcceivcd 21 Jl?ly 1975 We present a theoretical model for describing spin coherence in photoexcited triplet states in zero-field under the influence of vibronic relaxation. From a comparison with experimental results in parabenzoquinone we obtain information about the properties of the excited
The three spin-lattice relaxation rates for the triplet state of ncridine in zerc-field have been determined in a biphenyl host from 1.7-3.2 K. The mean relaxation rate for the triplet state of phcnanthrene was determined in a biphenyl host from 1.3-13 K Two conclusions of a more general nature emer
