Combined deuterium labeling and appearance potential measurements to uncover competing reaction mechanisms in the electron‐impact‐induced loss of water from cyclohexanol

Abstract

Abstract The appearance potentials for loss of H 2 O and DOH from the constitutional isomers 3,5‐dideuterocyclohexanol and 4,4‐ dideuterocyclohexannol show, in agreement with proposals based on stereoselectivites, that 1,3 loss of water is energetically more costly than 1,4 loss of water.
