Structure and dynamics of radical cations of selectively deuteriated cyclohexanes: an ESR and ab initio study

, 1998
An ESR study was carried out to elucidate the static and dynamic Jahn-Teller structures of the radical cations of selectively deuteriated cyclohexanes in a cC(6)F(12) matrix, formed by exposure to ionizing radiation at low temperature.

Vicinal Deuterium Perturbations on Hydrogen NMR Chemical Shifts in Cyclohexanes

, 2016
The substitution of a deuterium for a hydrogen is known to perturb the NMR chemical shift of a neighboring hydrogen atom. The magnitude of such a perturbation may depend on the specifics of bonding and stereochemical relationships within a molecule.
