✦ Synopsis

Pulse ndrolysls studies show that phenokyl nchcd rcacis .11 diflusion controlled r&s. Conccntratlons on the tlmc scJc of stopped flow c\pcriments cannca be substantially above IO -s hl so that in the absence of resonance crhanci ~n:nt the Ramzi spectrum rcportcd by Shmdo and Hmush~ cannot be dsagncd to phcno\yl ndlal. Shndo and Hlraishi [I ] III stopped flow studies of the oxldatlon of phenol by ceric ion have reported ;I Raman spectrum which they assigned to pllenoxy (phenoxyl) radical by reference to the ESR studies of Stone and Waters [2] on the same system, Phenoxyl radrcal is, however, known to be a very reactive inter-
