NMR studies on dimethyl selenide and dimethyl telluride oriented in the nematic phase of a liquid crystal

Abstract

1H NMR spectra of dimethyl selenide with 13C and 77Se satellites and of dimethyl telluride with 13C, 123Te and 125Te satellites have been investigated. The structural information has been derived and is found to be in good agreement with microwave results for dimethyl selenide. For dimethyl telluride our results disagree with earlier data obtained by extrapolation from similar molecules.
