Absolute rate constants and their temperature dependencies were determined for the addition of hydroxymethyl radicals ( C H 2 0 H ) to 20 monoor 1,l-disubstituted alkenes (CH2 = C X Y ) in methanol by time-resolved electron spin resonance spectroscopy. With the alkene substituents the rate constants
An absolute value of k, of ethyl radicals at 860 f 17Β°K 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 860Β°K. An error of as much as a factor of 2 in k, would be surprising, but possible. The value of lO'OM-'
