✦ Synopsis

Abstract

The correlation between the puckering angle of the four‐membered cycle and ^4^J has been obtained from analysis of the PMR spectra of some 2‐substituted azetidines and oxetanes. The absolute values of ^4^J~cis~ and ^4^J~trans~ were found to decrease with decreasing of the puckering angle.

## Abstract Proton magnetic resonance spectra of several mono‐ and disubstituted benzaldehydes were studied using CW, INDOR and double resonance techniques. It was verified that substitution in the __para__ position has no effect on the long‐range coupling of the aldehydic proton with the ring prot
