## Abstract A study is presented of the dependence on conformation of one‐bond carbon‐proton coupling constants in three 1‐4‐linked disaccharides. Calculated ^1^__J__(CH) values are based on the FPT formulation in the semi‐empirical INDO MO method. The configuration at the anomeric carbon influence

The p-proton hypertine coupling constants in S-substituted ethyl radicals CH2-CH2-X (X=CHJ, NH2, OH, F, SiH9, PH2, SH, Cl) were computed as a function of the rotational angle (Y about the C.C, bond by ab initio calculations at the UHF/DZ+d level. They follow the relation aHg (0,a) =A+ B cos\*O + Cco
