The factors giving rise to artifacts in the NMR spectra of 33 S and other quadrupolar nuclei of low magnetogyric ratio are examined and some tests for their detection are proposed. The effects of line width and probe ring‐down time on the observed signal intensity are considered and a quantitative relationship is described. Sulphur‐33 NMR spectra of sodium sulphide solutions are reported which differ substantially from those recently published. The reasons for these and other differences between reported spectra are explained in terms of experimental artifacts of the types described.
