โฆ Synopsis
Stark effects bn the phosphorescence spectra of p-benzoquinone have been studied ;n nnphtbalcne crystals at temperatures between 1.7 and 30 K. The exDerimenta1 data establish that *be band spiitting of 24 cm-t arises from a double mini-* mum potential in the Tr state.

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\*
