The laser flash photolysis ofpyrazine in water and in organic solvents has been examined. The "(II, a\*) state in water has absorption bands at 230. = 260, = 295, =. 640,700 and 8 10 nm, and decays with k = 2.2 X 10' set-' . It is quenched by oxygen with k = 3.2 X 10' &I-'set-' and by various H-atom
