31.Further optimization of our spectrometer has extended our spectral coverage. Spectra up to 130 are now attainable in favorable cases.6

34.The difference between the temperatures of the simulation and the experimental spectra is relatively small and is ignored in this article, where the trends in the dynamics as a function of composition are our primary consideration. The simulation temperature of 25 °C is the temperature at which the potentials for the neat liquids were parametrized (see Refs. 35363738).

42.Two points stand out: (1) the equilibration period is significantly longer than those of numerous earlier studies (Refs. 4, 20, 22, and 26), and (2) the equilibration period depends on which system is being investigated and on the composition of the mixture. The individual molecules require adequate time to explore various configurations within the system, and their (usually) randomly distributed starting positions may be far from equilibrium. The slow relaxation of the RDFs of aqueous mixtures has been noted by Laaksonen et al. (Ref. 21).

45.A Kramers–Kronig calculation requires the high frequency index of refraction. The indices of refraction for the neat liquids at 20 °C are 1.359 (acetone), 1.344 (acetonitrile), 1.328 (methanol), and 1.333 (water) (Ref. 46). Ideal values of the indices of refraction were used for the mixtures.

52.Two difficulties arose with analyzing the experimental spectra: (1) Because the Gaussian curve is symmetric, fitting it to the slightly asymmetric absorption band of water would result in values of the peak position that are too low. (2) The lower frequency side of the absorption band was inaccessible for some compositions. To handle these difficulties systematically, the curves were fit to as much of the spectra as appeared symmetric. The agreement between the absorption band and the fitted curves over the selected range was good. The fitted values of the peak widths are expected to be slightly low, but should follow changes in the actual peak width.
53.For acetone and acetonitrile mixtures, which have no high frequency librations, the ideal peak position and width are the same as those of neat water. The peak positions of methanol and water are almost identical, but the widths differ. Therefore, the ideal peak positions are very similar to those of the neat liquids, whereas the widths change significantly with mixing.
