Response to Comment on "Energetics of Hydrogen Bond Network Rearrangements in Liquid Water"

Nilsson et al. raise two central issues regarding our recent paper on the energetics of hydrogen bond (H bond) rearrangements in normal and supercooled liquid water. The first concerns the quality of our temperature- dependent x-ray absorption (XA) spectra, which Nilsson et al. argue exhibit nonlinear saturation effects. The second point concerns the appropriateness of the spectral analysis we employed in, wherein it was assumed that specific H- bonding configurations are spectrally resolvable.
