    • note
    • The fraction of thermalized DCl molecules undergoing interfacial D → H exchange was measured to be 7% at 273 K in ref 14 versus 3% at 291 K here. We have not yet verified this temperature effect or explored it in more detail. The 291 K values reported here have been reproduced repeatedly. We have verified that Nal enhances both interfacial exchange and trapping desorption at 291 as well as at 273 K.

    • note
    • The Nal activity coefficients in Figure 3 may be analyzed in more detail through models such as the mean spherical approximation or the solvent removal hypothesis of Robinson and Stokes. An approximate fit using the second model yields two to three glycerol molecules per NaI with å = 5-2 Å. See ref 1, eq 9.27.
