Abstract

^119^Hg NMR chemical shifts of the stable mercury species HgCl with n = 0–4 were determined by a least‐squares algorithm from ^199^Hg chemical shifts measured in 50 mM aqueous mercury solution as a function of the chlorine concentration at 25°C. The concentrations of the corresponding mercury species in the solutions necessary in this special procedures were calculated by using published equilibrium constants. The results relative to dimethyl‐mercury are −2256 ppm (Hg^2+^), −1897 ppm (HgCl^+^), −1560 ppm (HgCl~2~), −1436 ppm (HgCl~3~^−^) and −1152 ppm (HgCl) with maximum errors of ±5 ppm.
