Liquid water sustains life on earth, but its physical properties remain mysterious among scientific researchers. Recently, a team of Swiss researchers used existing THz spectroscopy techniques to measure liquid water's hydrogen bonding. Future efforts with this technique could one day help explain water's peculiar properties. The team reports their findings in The Journal of Chemical Physics, from AIP Publishing.
"What makes this paper special is the aspect of THz spectroscopy of a liquid. In the THz range, we make spectroscopy explicitly of the intermolecular degrees of freedom of the system in the study, to contrast it to intramolecular degrees of freedom," said Peter Hamm, an author on the paper. "With THz spectroscopy, we can very directly look at the hydrogen bonding between various water molecules."
