## Abstract No reliable rate constant is available for the selfโreaction of __tert__โ;butoxy radicals. We have set up a competition between hydrogen abstraction and selfโreaction of __tert__โbutoxy radicals in a flash photolysis electron spin resonance study to extract this information. Experimenta
An absolute value of k, of ethyl radicals at 860 f 17ยฐK of 4.5 X l o 9 M-l.sec-' was determined under VLPP conditions, where the value of k,/k," should be about M. Thus k,"(M-'.sec-') -10' 0 at 860ยฐK. An error of as much as a factor of 2 in k, would be surprising, but possible. The value of lO'OM-'
