The microscopic structure of sub-and supercritical water has recently been determined by novel liquid X-ray diffraction using an imaging plate detector and neutron diffraction with isotopic substitution. The X-ray and neutron results are compared with those obtained by Monte Carlo and molecular dynamics computer simulations and Raman and infrared spectroscopy. A recent attempt to obtain the three-dimensional structure of supercritical water by spherical harmonic expansion method is also described Discussion is focused on the degree of hydrogen bonding in supercritical water and its correlation with physicochemical properties.
