Abstract
Deuterium isotope effects on olefinic proton chemical shifts in a seri es of deuterated cis- and trans-stilbene isotopomers have been determi ned and analysed. The effects exhibit conformational and solvent depen dence. The sign and magnitude of the effects are governed by the addit ivity rule. An opposite trend between the effects at the olefinic prot on and those previously observed at olefinic carbon has been found and discussed for closely related compounds. (C) 1997 Elsevier Science B.
