Chemically induced dynamic electron polarization (CIDEP) spectroscopy of radicals generated in the photoreactions of polyols: the mechanisms of radical dehydration

  • I. A. Shkrob
  • J. K. S. Wan


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.
