✦ Synopsis

Abstract

The chemical shifts of the N‐methyl signals for a number of thio‐oxamide and oxamide derivatives are unambiguously determined in the solvents chloroform, carbon tetrachloride, benzene, chlorobenzene, o‐dichlorobenzene and nitrobenzene. The ASIS effect is discussed. The temperature dependence of the absolute shift and of the relative shift differences of both methyl groups of the N,N‐dimethyl derivatives are studied.

## Abstract A PMR study of solvent effects on some __p__‐substituted phenyltin chlorides (substituents = CH~3~, (CH~3~)~3~C, CH~3~O) is reported. Co‐ordination of solvent molecules to the tin atom leads to an unusual low field shift of the __o__‐ring protons. The results for __p__‐tolytin trichlori

## Abstract An accurate measurement of the chemical shifts and the coupling constants of some disubstituted acetophenones has been made. The acetophenones studied contained nitro, bromo or amino groups substituted in either the 3,4 or 2,5 positions. For compounds with no substituent adjacent to the

## Abstract The structures of the atropisomers of __o__‐hexaphenylene are confirmed by their proton magnetic resonance spectra. The centrosymmetrical isomer **1a** gives rise to an AA′BB′ spectrum, whereas the helical isomer **1b** displays an AA′BB′ spectrum for two of its aromatic rings and an AB
