The 13 C and 1 H NMR spectra of six N‐5 ′ ‐methylsalicylideneanilines have been studied. Correlations of the chemical shifts of C‐α (azomethine carbon) and C‐4′ with the σ, F, R , σ 1 and σ R 0parameters have been examined for N‐5 ′‐methylsalicylideneanilines, and also for N ‐benzylideneanilines and N ‐salicylideneanilines. The results suggest that the first compounds have a nearly planar conformation whereas the second and third type of derivatives have a twisted conformation.
