Nuclear Relaxation in Adulterated Hydrogen
Journal Article

· Journal of Chemical Physics
The proton spin-lattice relaxation time T/sub 1/ was measured in normal hydrogen and in mixtures with 12 other gases as a function of density and composition at room temperature. Cross sections for m/sub j/ transitions of the H/sub 2/ molecule deduced from the Bloembergen-Schwinger formula are interpreted qualitatively on the basis of electric multipole moments as measures of the anisotropy of the intermolecular forces, using the transient approximation. This approximation is justified in the case of H/sub 2/-CO/sub 2/ mixtures on the basis of the temperature dependence of T/sub 1/. The assumptions of the BloembergerSchwinger formula are discussed, and an experiment is proposed to determine the connection between two correlation times which appear in the theory.
