摘要: Natural xenon, contained in a ceil at a pressure of 6.5 atm, is frozen from 303 to 137 K on an WP-80SY NMR spectrometer. NMR signals of 129Xe atoms in gaseous, liquid and solid phases are measured at various temperatures, We found that the chemical shift of NMR signal of liquid 129Xe (expressed as ΔH) is directly proportional to the density of the sample with a coefficient of (4.73±0.05)×10-7; and the chemical shift of NMR signal of solid 129Xe (expressed as ΔH) is nearly proportional to the density of the sample with a coefficient of (5.00±0.08)×10-7.
