✦ Synopsis

It is found by nanosecond laser flash photolysis at 355 nm that triplet energy transfer from triplet benzophenone ('BP*) to N,Ndimethylaminonaphthalene (RNMe,) occurs to yield triplet RNMe, with an efftciency of 0.58 in acetonitrile ( ACN) whereas electron transfer from RNMea to 3BP* takes place to produce the benzophenone anion and RNMe, cation radicals with an efftciency of 1 .O in ACN: Ha0 (4: 1 v/v) at 295 K. A possible mechanism for electron transfer of the BP-RNMe, system in the presence of Ha0 is discussed.

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
