Sulfur-33 Nuclear Magnetic Resonance Spectra for Sulfates

Abstract

The sulfur-33 NMR spectra at natural abundance for sodium, cupric, cadmium and cesium sulfates besides sulfuric acid were recorded. Ferric and nickel sulfates did not give spectra because of their strong ferromagnetism. A very sharp peak at 33.5ppm downfield from ammonium sulfate was observed for sodium thiosulfate. Dimethylsulfate and ethane sulfate also showed spectra with a poor signal-to-noise ratio, with accumulations of 10⁵ transients at 19.19MHz.
