Abstract
The radicals formed from pyridine, 3-methylpyridine, 3,5-dimethylpyrid ine, 2,6-dimethylpyridine and 2,4,6-trimethylpyridine by attack of H, e(aq)-, OH and O.- in aqueous solutions were investigated by pulse rad iolysis in the pH-range 1-13.8. The UV-vis. absorption spectra as well as the formation and decay kinetics for the protonated and unprotonat ed forms of the methylpyridine radicals studied are presented. The pK( a)-values for the OH-adducts were determined.
