## Abstract Fourier transform carbonโ13 nuclear magnetic resonance spectra have been obtained and interpreted for some 2โsubstituted tetrahydropyrans. The effects of the substituents on ฮฑ, ฮฒ, ฮณ and ฮดโcarbon atoms are discussed. Using suitable reference compounds the ฮณโparameter can be used for quan

## Abstract Carbonโ13 n.m.r. spectra have been obtained for some methyl and phenyl substituted 2__H__โazirines. The higher field resonance of Cโ2 than that of the corresponding aziridine carbon is interpreted in terms of ring strain. Substituent effects on the chemical shifts of the azirine ring ca
## Abstract The ^13^C n.m.r. data of a variety of 4~eq~โ and 4~ax~โsubstituted adamantanones and bicyclo[2.2.2]octanones are presented. It is shown that for a number of carbons the chemical shifts cannot be predicted by a given additivity rule. The deviations of the observed chemical shifts from th
REFERENCE DATA causes the electron density to be comparatively lower at C-3 and C-5 than at C-2 and C-4, so that the former signals resonate at lower fields. Distinction between the signals of the C-2/C-4 and C-3/C-5 pairs was achieved by comparing the C-H coupling patterns of 5 and 1. Compounds 1,
