The continuum model treatment of long-range intermolecular forces is applied to the effect of dispersion interaction on NMR shifts. The theory is applied to infinitely dilute solutions of nonpolar molecules in nonelectrolytes and to pure gaseous substances. Calculated shifts are in semiquantitative agreement with the experimental values; the general trends are accurately predicted. Polar solvents show no unusual behavior. Several empirical relations, previously proposed, are derived and discussed.
