1-Methylpyridinyl and 4-alkyl-1-methylpyridinyl (alkyl= methyl, ethyl, isopropyl, and t-butyl) radicals were generated photolytically from their dimers in solution. Hyperfine splitting constants for these radicals were assigned and the temperature dependence was discussed. Absolute dimerization rates of these radicals in the range of− 50–− 100° C were determined by analyzing the ESR signal decay during the dark period. A nearly constant ...
