Abstract

The ^1^H n.m.r. spectra of 1,4,5‐triazanaphthalene, benzothiazole and quinoline oriented in nematic liquid crystalline phases have been analysed and the parameters used to determine the interproton distance ratios.

## Abstract The NMR spectrum of phenazine, the tricyclic diazine, oriented in a nematic phase is investigated. The ratios of the interproton distances are determined. They do not deviate significantly from the corresponding values in quinoxaline oriented in a thermotropic solvent.

## Abstract ^1^H n.m.r. spectra of __N__‐phenylmaleimide have been investigated in isotropic as well as nematic phases; the chemical shifts, the direct dipolar and the indirect spin–spin coupling constants have been determined. The direct dipolar coupling constants are consistent with rapidly inter

## Abstract It was found that analysis of the ^1^H‐NMR. signals (at 360 (preferably) and/or 100 MHz) of the protons at C (4) and of the equatorial α‐proton at C (6), particularly when these are located in the 2–3 ppm region and therefore convenient for detection and identification, may be of valuab

## Abstract The proton spectra of phenyltin trichloride including ^119^Sn‐ and ^117^Sn‐satellites have been analysed in isotropic and in oriented solvents. The indirect as well as the direct proton‐proton and proton‐tin coupling constants have been measured. From these the proton‐proton and proton‐
