Proton magnetic resonance spectroscopy has been used to study the exchange reaction which is responsible in aqueous solution for averaging the two methyl proton signals of trimethylaquabipyridineplatinum(1V) cation. The dependence of the rate upon cation concentration, pH, added sulphate ion, and temperature and the appearance of 195Pt satellites in the 2,2'-bipyridine proton spectrum lead to the conclusion that the reaction being followed is exchange of a coordinated water ligand with the bulk solvent.

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.
