Scientists Solve H 2 O Mystery

For the last 50 years, scientists have sought to understand the biochemical and physical processes that take place in liquid H₂O. They employed such methods as dielectric relaxation, spectroscopy and nuclear magnetic resonance, but these methods have yielded ambiguous data.
Now a group of research-ers from the Institute for Atomic and Molecular Physics in Amsterdam, The Netherlands, has employed a femtosecond mid-IR pump-probe spectrometer to reveal detailed information on the dynamics of how selected molecules interact in the liquid phase.
