    • Since a major goal of this paper is to test different versions and generalizations of instantaneous-pair theory against exact liquid dynamics, both the theory and the calculations we present here will be completely classical. See Refs. 20, 23, and 27 (and references therein) regarding the magnitudes and applicability of relevant quantum correction factors.

    • Assuming the force being driven is instantaneously exponential is the analog of the basic (harmonic) INM assumption that the force doing the driving is instantaneously linear. Both are exact at short times.

    • In the solid state context it is frequently suggested that such combination bands contribute relatively little to high-frequency relaxation. See Refs. 21 and 22. However the issues here are first, whether the same phenomenology should apply to liquids, and second, what happens as the frequency decreases.

    • note
    • Using a conventional definition of the first solvation shell would palce most of the shell to be outside the range of mnn distances (Ref. 53) and therefore outside the (presumably most interesting) repulsive-force region of the solute-solvent interaction. Moreover, as with the polar solvent example (Ref. 41), such solvents would produce divergences in the nonlinear INM formalism. For the purposes of nonlinear INM theory, then, we define the first solvation shell as those solvents closer to the end site of the solute than σ (roughly the maximum of the solute-site/solvent radial distribution function). This definition leads to an average of 1.46 solvents in the first shell under our conditions.

    • The basic issue is that quantum mechanics automatically delocalizes intermolecular positions whereas INM theories are valid only locally. There is therefore no a priori reason to expect that the same instantaneous harmonic potentials that govern the short-time classical dynamics should have any relevance to quantum mechanical bound states in a liquid. Some interesting quantum mechanical generalizations of INM ideas have, nevertheless, been explored by J. Cao and G. Voth, J. Chem. Phys. 101, 6184 (1994)
