The transient absorption bands dm 3 9 Οͺ1 ( Ο 330, 525 nm, k Ο 5 Ο« 10 mol max f obtained on pulse radiolysis of N 2 O-saturated neutral aqueous solution of 4,4Π-thiodi-Οͺ1 s ) phenol (TDPH) are due to the reaction of TDPH with ΠΈOH radicals and are assigned to phenoxyl radical formed on fast deprotonat
Formation of cation radicals by pulse radiolysis of metalloporphyrins and chlorophyll a in 1,2dichIoroethane is reported. Demetalation of the metalloporphyrin by radiolytically produced HCl is also observed. Rate constants for demetalation of ZnTPP and Chl a are 1 .I X IO8 and = 3 X IO8 h!-' s-I\_ O
