Abstract

Proton magnetic resonance spectra of benzo[b]selenophene including $^{77}Se$ satellites have been investigated in thermotropic liquid crystal solvents. Relative proton-proton and proton-selenium distances have been derived from the dipolar couplings. A comparison of the results on benzo[b]-furan, -thiophene and -selenophene and the application of bond polarisation hypothesis indicate significant solvent effects in the liquid crystal formed by an eutectic ternary mixture of propylpentyl- and heptyl-bicyclohexylcarbonitrile.
