Recently several investigators reported opti-aZ detection of ESR transitions in phosphoresent triplet states of various molecules [l-3]. he experiments were done by sweeping the magetic field at fixed microwave frequency. In con-;ast with the normal ESR detection method. the Jsorption of microwave p

The ENDOR spectrum of the high-frequency ESR transition of phosphorescent quinoline in zero field is in vestigated. The findings are in accord with a recent analysis of Buckley et al. From the observed ENDOR ftequencics the quadrupolar splitting of the 14N nucleus in the phosphorescent state is dete
