Long-Range Deuterium-Induced Isotope Effects on H-1 Chemical Shifts in cis- and trans-Stilbene

Deuterium isotope effects on olefinic proton chemical shifts in a series of deuterated cis- and trans-stilbene isotopomers have been determined and analysed. The effects exhibit conformational and solvent dependence. The sign and magnitude of the effects are governed by the additivity rule. An opposite trend between the effects at the olefinic proton and those previously observed at olefinic carbon has been found and discussed for closely related compounds.
