The relationship between the nature of the reactive triplet state of phenazine, as well as its mono-, di-, and tetrabenzo derivatives, and their reactivity in the formation of triplet exciplexes with amines has been investigated. It has been shown that the reactivity of triplet excited states of phenazines is determined mainly by the presence of vibrational mixing of the lower T/sub 1/ and T/sub 2/ triplet states with different electronic configurations and the position of the T/sub 2/ level. The total reaction rate is determined by the sum of the rates of the processes with the participation of the T/sub 1/ and T/sub 2/ states.
