A study of the structure of 4-chlorophenyl methyl selenide by nuclear magnetic resonance of liquid crystalline solutions

Abstract

Proton and deuteron spectra of samples of 4-chlorophenyl [²H₃]methyl selenide dissolved in the liquid crystal solvent E9 have been recorded. Their analysis was a first step towards analysing the proton spectrum of the non-deuteriated compound, including the satellite spectra from molecules containing 7.6% of ⁷⁷Se. The dipolar couplings were used to determine the two C–Se bond lengths and to test models for the rotational potential describing the relative conformation of the phenyl ring and the C–Se–C plane.
