Potential Parameters

Proton spin-lattice relaxation times T1 were measured in mixtures of H2 with N2O as a function of density, composition, and temperature (200–400 K) in the region where [Formula: see text]. These data, along with the data obtained by Lalita and Bloom for H2–CO2, were interpreted, using Bloom–Oppenheim theory, to obtain the anisotropic intermoleeular potential parameters. Two models, (i) the Lennard–Jones (12–6) potential (LJP) and (ii) the modified Buckingham (exp-6) potential (MBP), were used to represent the isotropic part of the intermolecular potential. The relative anisotropy in the attractive r−6 term and the quadrupole moments of N2O and CO2 as obtained from MBP model are in better agreement with the values obtained from the polarizability data and the reported values, respectively, than those obtained from the LJP model.

Potential Parameters

The intermolecular potential parameters of solid Ne, Ar, Kr, and Xe are calculated for a modified Buckingham exp–6 potential using crystal data of the sublimation energy and lattice spacing extrapolated to 0 °K. The parameters ε and σ in the exp–6 potential[Formula: see text]are compared for selected AN ("all neighbor") models with those calculated by Mason and Rice (1954) from gaseous data.
