摘要：

The rotational barrier in 4-benzoyl-1-thia-4-azacyclohex-2-ene has been investigated by total line-shape analysis of variable temperature1H nmr spectra in acetonitrile-d3. Separate treatment of the vinyl and methylene signals yielded sets of values for activation parameters which were in excellent agreement. Assignment of the major and minor rotational isomers mas made from chemical-shift data derived from the13C nmr spectrum at 243 K in acetonitrile-d3. © 1976, Canadian Science Publishing.
