Abstract
A revised expression for the π electron contribution to proton-proton coupling is presented. Calculations using this expression give much smaller contributions than were obtained from the earlier expression of Karplus. Even for coupling over five bonds it is predicted that a significant part of the coupling arises from a σ electron mechanism.Keywords
