DENSITY DEPENDENCE OF (129)Xe CHEMICAL SHIFTS IN MIXTURES OF XENON AND OTHER GASES.
Abstract
Unlike other chemical shifts in gaseous systems which have been found to have strictly linear dependence on density, it was found that the 129Xe chemical shift in pure xenon gas to have a quadratic and cubic dependence in addition to the dominant linear dependence on density. This implies the importance of three or more body interactions in xenon. In mixtures of xenon with another gas (Ar, Kr, CO2, HCl, CH4, CH3F., CH2F2, CHF3, CF4), the dependence of the 129Xe chemical shift on the density of the other gas was found to be linear within experimental error, and varying from 2300 to 11,700 ppm/mole/cc. These shifts are orders of magnitude greater than the reported H and F shifts in gases. (Author)
