Abstract

A large group of polarized radicals derived pom polyatomic alcohols heretofore unexplored by CIDEP techniques are characterized in viscous media. The TR ESR technique is shown to be capable of unravelling the mechanisms of the complicated dehydration processes of the primary olyl radicals in neutral, acidic and basic media.
