27. It is not necessarily possible to perform a rigorous resolution of an arbitrary motion of the solvent into a linear combination of INMs. The INM density of states does have only a finite bandwidth. Nonetheless this resolution can often be accomplished approximately, as illustrated by linear INM solvation theory and by the INM theory of vibrational population relaxation, for example. One can also systematically enlarge the available bandwidth by coupling to INMs at higher powers than linear. Larsen, R. E.; Stratt, R. M. In preparation. The present paper will be concerned with dynamics at the linear level.

48. An alternative approach to predicting frequency-dependent vibrational friction using INM theory is explored in: Schvaneveldt, S. J.; Loring, R. F. J. Chem. Phys. 1995, 102, 2326. Schvaneveldt, S. J.; Loring, R. F. J. Chem. Phys. 1996, 104, 4736. Schvaneveldt, S. J.; Loring, R. F. J. Phys. Chem. 1996, 100, 10355. For the approach described in this paper, we employ the notation that a (nonboldface) subscript R denotes the cosine transform (the real part of the Fourier-Laplace transform), whereas a boldface subscript R refers to a result obtained for a single liquid configuration. We also note that eq 2.9 is valid only for ω ≠ 0, since we have omitted a formal contribution from an additional term proportional to δ(ω).

86. An interesting complementary exploration of precisely the same kinds of distinctions is provided by: Stephens, M. D.; Saven, J. G.; Skinner, J. L. J. Chem. Phys. 1997, 106, 2129.
87. The suggestion has been made that while electrostatic forces can be quantitatively important, their effects may not always be as dramatic as that seen in ref 17. See: Benjamin, I.; Whitnell, R. M. Chem. Phys. Lett. 1993, 204, 45.

90. 3CN reveals much the same kinds of mechanistic and time-scale similarities between Lennard-Jones-mediated solvation and vibrational relaxation, but somewhat less similarity in the depths of the minima of the corresponding G(t) functions.
91. A similar square-root-like dependence was observed for the number of ""participating" modes when we carried out a finite-size-scaling study for vibrational relaxation in atomic fluids. See ref 26 (footnote 85).
