The 220 MHz p.m.r. spectra of 4-(4′-nitrothiobenzoyl)-2,6-dimethylmorpholine (1) provide evidence for the progressive freezing of the librations of the thioamide group around the C(S)—Ph bond as the temperature is lowered. This is supported by spectral data on related compounds in which the aromatic and hetero-ring substituents are altered.

Abstract Disulfiram was determined in disulfiram drug substance and tablets by proton magnetic resonance (PMR) spectroscopy at the 100–480 mg level and by a colorimetric technique involving cuprous iodide at the 50 mg level. The tablet excipients do not interfere in the analysis. The average result for disulfiram in a tablet composite was 100.8±1.4% of label claim by PMR and 100.7±0.4% by the colorimetric method.
