โœฆ Synopsis


Time-resolved ESR spectra have been observed for the lowest excited triplet states of 1-nitronaphthalene and 1,4dinitronaphthalene in EPA at 77 K. The results show that the sublevel preferentially populated by intersystem crossing is T,, in both molecules studied (y is close to the in-plane long axis of the naphthalene ring) and there is a strong vibronic coupling between the 'rot* and the close-lying 'nx* states.

A time-resolved ENDOR (TRENDOR ) apparatus was constructed and applied to observe hyperfine couplings in the photoexcited triplet (Tr ) state. The TRENDOR spectra of the Tt states were observed both in mixed crystals and glass. The hypertine coupling constants were obtained at 4-100 K for quinoxalin
