Proton NMR spectra including 13C- and 77Se-satellites in organoselenium compounds oriented in the nematic phase: Part 1: The spectrum of 2,1,3-benzoselenadiazole

Abstract

The vibrationally corrected structure of 2,1,3-benzoselenadiazole is derived from the proton NMR spectrum including 13C-H and 77Se-H satellites, in a nematic solvent. The results indicate considerable bond-fixation in the 6-membered ring.
