Rapid Water-Ion Dynamics Revealed

New spectroscopic techniques provide femtosecond details of water-ion interactions in solution
Department: Science & Technology
Keywords: water, hydrogen bonds, ions, dynamics

New spectroscopic techniques are providing some of the most detailed pictures yet of the behavior of water molecules on femtosecond time­scales (Science 2010, 328, 1003 and 1006). Ubiquitous liquid water, with its networks of evanescent hydrogen bonds and its vital interactions with biological and atmospheric molecules and ions, remains mysterious. In one study, Minbiao Ji of the SLAC National Accelerator Laboratory and colleagues used two-dimensional infrared spectroscopy to verify a recent . . .
