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
