✦ Synopsis

Microws;e induced delayed phosphorescence (h_fIDP) meastircments have been performed in the O-O bands of the phosphorescence spectrum of benzene dissokcd in two phases of cyclohexane. From the relative radiative rates for decay of ihe three zero-field levels it is concluded thnt on the average the symmetry of the electronic structure is lower than Dal,. In the monoclinic low tempenture stable phase of cyclohesane (phase If) the stnxtare is appro~i~tely anti~uinoida!, and in the metastabte phase 111 it is approximately quinoidal
