Measurement of the ¹²⁹Xe NMR Chemical Shift of Supercritical Xenon

Abstract

Abstract The measurement of the 129 Xe Nuclear Magnetic Resonance (NMR) chemical shift as a function of density is reported. The apparatus used in this study enabled us to measure the 129 Xe NMR chemical shift in the supercritical state up to a pressure of about 70 MPa, i.e. , a density of 440 amagat 1 at 298 K.
