Comment on "Energetics of Hydrogen Bond Network Rearrangements in Liquid Water"
A. Nilsson, Ph. Wernet, D. Nordlund, U. Bergmann, M. Cavalleri, M. Odelius, H. Ogasawara, L.-Å. Näslund, T. K. Hirsh, L. Ojamäe, P. Glatzel, L. G. M. Pettersson.
Abstract: Smith et al. (Reports, 29 October 2004, p. 851) reported a temperature-dependent x-ray absorption study on liquid water. We argue that both the measurement and the data analysis have serious shortcomings. The spectra are affected by experimental saturation effects, and the analysis suffers from incorrect assumptions for x-ray absorption spectroscopy.

Response to Comment on "Energetics of Hydrogen Bond Network Rearrangements in Liquid Water"
J. D. Smith, C. D. Cappa, B. M. Messer, R. C. Cohen, R. J. Saykally.
Abstract: We demonstrate that the spectra reported in our study are free from artifacts induced by saturation effects. Furthermore, our analysis of the energetics of hydrogen-bond rearrangement is in perfect agreement with temperature-dependent populations previously reported by Wernet et al.
