The phosphorescence spectra of <I>p</I>-benzoquinone (PBQ) have been studied at 4.2 K in isostructural crystals such as <I>p</I>-dichlorobenzene (DCB), <I>p</I>-bromochlorobenzene (BCB), and <I>p</I>-dibromobenzene (DBB); and in their binary mixed crystals. The variable phosphorescence band patterns observed are interpreted in terms of anisotropic local-field effects of the host environmental molecules. A similarity of the phosphorescence intensity distribution between two systems of PBQ/BCB and PBQ/(0.5 molar fraction of DCB+0.5 molar fraction of DBB) is a manifestation of the existence of effective local-fields in the crystals.
