Abstract

Additive shielding parameters for olefinic protons were derived for 36 functional groups by means of a least squares procedure applied to 4298 chemical shifts. Additional shielding parameters for a further 7 functional groups were obtained by assuming simple additivity. A number of conspicuous exceptions to the calculated values are listed.
