Abstract : The photodissociation study of a purified tetrakis (p-octylphenyl) hydrazine (TPOPH) in benzene (0.0001M) has shown that the recombination rate constant is independent of wavelength in the region of the two major absorption peaks. The recombination follows second-order kinetics for at least 2.5 half-lives. The average initial half-life is 35.4 = 2.4 msec, excluding the low absorption region at 500-600 millimicrons. At 560 millimicrons the decay is first order. It is not clear whether this reaction is associated with TPOPH or with impurity.
