## Abstract The torsion angles of __trans__‐pyridinalanilines and __trans__‐benzylideneanilines were derived from the chemical shifts of the __para__‐carbon atoms. The N‐torsion angle is between 33 and 59°. For the C‐torsion angle, a value of approximately 10° is obtained for the benzylideneaminopy

✦ Synopsis
Abstract
The ^13^C NMR spectra of all trans‐styryldiazines, methyldiazines and trans‐styrylpyridines have been fully assigned. Empirical shift increments were obtained for the chemical shifts of the carbon atoms; these are discussed in the light of theoretical considerations.

A detailed analysis of the -C NMR spectra of trans-stilbene and ten deuteriated trans-stilbenes has been undertaken. Some unusual deuterium isotope effects on carbon-hydrogen spin-spin coupling constants could not be explained by the ordinary primary and secondary isotope effects. The positive and n
