Mapping the structure of protonated water clusters Water molecules are continuously forming short-lived networks called clusters. These can in turn bind positively charged protons, and such clusters can provide active functional groups in proteins. Using infrared spectroscopy, it is possible to determine the bond strengths, geometrical structures and chemical properties of protonated water clusters. In order to measure the spectrum of molecular vibrations in clusters it is, however, necessary...
