Response to “Comment on ‘An interpretation of the low-frequency spectrum of liquid water’ ” [J. Chem. Phys. 118 , 452 (2003)]

Abstract

We remark the fact that even if the frequency peak around 60 cm−1 in the low-frequency spectrum of liquid water at room temperature can have a transversal component, it is a general feature of all sorts of liquids at ambient conditions. Conversely, the frequency around 170 cm−1 is only present in the spectra of associated liquids at ambient conditions, since although this mode is seen in the spectra of simple nonassociated liquids at supercooled states, it vanishes as temperature rises.
