## Abstract ^15^N Chemical shifts of __cis__‐decahydroquinoline, __N__‐methyl‐__cis__‐decahydroquinoline, and of 19 methyl substituted NH‐ and NCH~3~‐__cis__‐decahydroquinolines are reported. Shift values of conformationally homogeneous compounds can be used to determine the chemical shifts of the
## Abstract Nitrogen and carbon electron densities of the toluidines and xylidines have been recalculated by the INDO method; previously published errors have been corrected. Although the nitrogen‐15 chemical shifts of these compounds still display the earlier suggested correlation with σ and total
## Abstract The ^15^N chemical shifts of 13 __N__‐methylpiperidine‐derived mono‐, bi‐ and tricycloaliphatic tertiary amines, their methiodides and their __N__‐epimeric pairs of __N__‐oxides were measured, and the contributions of specific structural parameters to the chemical shifts were determined
## Abstract The carbon‐13 n.m.r. spectra of several oxaziridines were measured. Aliphatic and aromatic __ipso__ carbon atoms __trans__ to the lone pair of nitrogen in oxaziridines were shifted upfield by __c.__ 9 ppm, and 3.4 ppm, respectively, in comparison with isomers of inverted configuration.
## Abstract The ^13^C chemical shifts for 1,3‐dithiane and 9 methyl substituted derivatives are reported. Only three of the methyl‐1,3‐dithianes were conformationally anancomeric and hence the conformational equilibria must be taken into account when deriving the values of the different substituent
