The results of polarized Stark effect absorption esperimcnts on the lower triplet states ofp-benzoquinone (PBQ)-h4 and -dq in single crystals at 1.8"K are reported. These measurements give strong support for the assignment of the lowest triplet state as triplet 3B transition at 18602.8 cm-' ,g (nn\*

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.
