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.
The zero-field parameters for the lowest n-e triplet state of pyrazine are determined using optical detection of the magnetic resonance in zero magnetic field. The values thus obtained are D = \* 0.33923 -+ 0.
