All arrangements and procedures for steady-state and time-resolved ESR were as described in [4]. The radicals Me,C and Me3C02CCH, were generated by photolysis of the corresponding disubstituted ketones. These undergo type-I cleavage from a short-lived triplet state followed by a fast decarbonylation

## Abstract No reliable rate constant is available for the selfβreaction of __tert__β;butoxy radicals. We have set up a competition between hydrogen abstraction and selfβreaction of __tert__βbutoxy radicals in a flash photolysis electron spin resonance study to extract this information. Experimenta
The thermolysis mechanism of di-tert-butyl and di-tert-amyl peroxide was investigated in a variety of solvents employing electron spin resonance in collaboration with the spin-trapping technique. The tert-amyloxyl radical was trapped for the Γrst time during the thermolysis of di-tert-amyl peroxide.
one obtains the electronegativity XNSF, = 3.3. If one plots the mean P F frequency of the phosphoryl halides against the sum of the electronegativities, one obtains a linear dependence, whence the electronegativity of the NSF2 group again appears as 3.3.
