    • Note that while orientational relaxation has been written about repeatedly, rotational energy relaxation per se has not been discussed all that much in the literature, at least for typical laboratory solutes and solvents. See, for example, (a) Padilla, A.; Perez, J.; Hernandez, A. C. J. Chem. Phys. 2002, 117, 6599.

    • Recent work on CN photodissociation suggests that the asymptotics of realistic photoproduct measurements may also reflect specific longer time scale features of the reaction. (S. E. Bradforth, private communication). Our work in this paper is concerned largely with sub-ps dynamics, so we will also ignore the possibility of these kinds of effects here.

    • This observation is also consistent with what one finds by looking at changes in the distribution of solvent orientations with respect to the solute bond vector. Doing so shows that it is right at the 1/4 rotation mark that the most probable orientation of Ar atoms in the innermost part of the first sol vation shell shifts from being along the OH bond axis to roughly 30° off the axis.
