A novel X-ray diffraction method for liquids using an imaging plate area detector has been successfully applied to constant-density measurements of water at high temperatures and high pressures covering the supercrital state. The radial distribution functions have shown that the local tetrahedral ice-like structure of water is ruptured above 416K and that the short-range O-O interactions at -2.9Å still exist by -40% to the coordination number of 3.9, however, with large fluctuation and distorted hydrogen bonding in dense supercritical water at 649K.
