## Abstract The ^1^H, ^13^C and ^77^Se chemical shifts have been measured for mononitrobenzo[**__b__**]selenophenes. For the homocyclic nuclei, the observed ^1^H‐ and ^13^C‐values calculated from the empirical increments of nitrobenzene. Anomalous effects are observed in the 2‐ and 3‐substituted de

## 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
A theoretical study is presented of the dependence on the hydroxymethyl group conformation of vicinal carbon-proton coupling constant 3Jc, n in a series of 16 hexopyranoses. Calculated 3Jc, H values for both anomers of o-glucopyranose (1), D-mannopyranose (2), D-allopyranose (3), D-altropyranose (4)
