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.
Using absorption-detected magnetic resonance (ADMR) in zero field on Cso in a frozen toluene/polystyrene glass at temperatures between 6 and 40 K we observed two distinct triplet states. Their zero-field splitting parameters were determined by ADMR double resonance to be 1Dil=(114.6+l)x10-4 cm-', ~E
