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
It is found that the triplet-triplet energy transfer (ET) reaction between triplet benzophenone ('BP\*) and l-naphthol (ROH) is competitive with the hydrogen atom abstraction (HA) reaction. The rate constant of ET is enhanced with an increase of solvent polarity while that of HA is reduced. A possib
