## Abstract ^77^Se and ^13^C chemical shift of 19 1,2,3βselenadiazoles are discussed in terms of substituent effects and conformaβtional behaviour of the molecules. It is shown that the ^77^Se chemical shifts of such compounds are suitable tools for chiral discrimination in diastereomeric compounds
Proton and carbon-13 spectra of benzyl compounds of the general formula (C,H,CH,),X with a large variety of X substituents have been measured. While a linear relationship between the CH, chemical shift and the substituent electronegativity was found both for lH and lac, large deviations from lineari
