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 axi

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
Transient ESR spectra have been observed for the lowest triplet states of naphthalene, quinoline (QN), quinolinium (QNH+), isoquinoline (iso-QN) and isoquinolinium (iso-QNH+) in ethanol at 77 K using a time-resolved ESR technique. With the aid of computer simulations, it is concluded that, following
