Chemically induced dynamic nuclear polarization during the photoreaction of triethylamine with carbon tetrachloride

Abstract

Enhanced absorption CIDNP is observed for the chloroform proton and for the terminal olefinic protons of NN-diethylvinylamine during photolysis of the triethylamine–carbon tetrachloride charge transfer complex in methanol and acetonitrile; this points to the formation of the singlet radical pair Et2NĊHMe–ĊCl3 as a primary reaction step.
