The first observation of 201 Hg NMR signals in the solid state is reported for potassium tetracyanomercurate(II), K 2 Hg(CN) 4 . NMR measurements of 201 Hg and 199 Hg were carried out at 4.70, 7.05 and 9.40 T. The ratio between the observed NMR frequency for 201 Hg and 119 Hg yields an accurate value for the ratio of their magnetogyric ratios, |γ( 201 Hg)/γ( 199 Hg) | = 0.369 1389(9). This value agrees well with that obtained from optical pumping experiments on mercury vapor in the gas phase. The 201 Hg NMR line shapes observed for solid K 2 Hg(CN) 4 are Lorentzian owing to efficient relaxation via the quadrupolar mechanism. In contrast, the corresponding 199 Hg NMR line shapes are Gaussian and much narrower.
