Abstract

A time-resolved ENDOR (TRENDOR) apparatus was constructed and applied to observe hyperfine couplings in the photo-excited triplet (T₁) state. The TRENDOR spectra of the T₁ states were observed both in mixed crystals and glass. The hyperfine coupling constants were obtained a 4-100 K for quinoxaline in single crystals of durene and p-dibromobenzene and for tetraphenyporphine (H₂TPP) in toluene glass. The time profile of the ENDOR signal was analyzed with population kinetics using a four-level system.
