Structure of supercritical water

This review paper gives the more up to date information on the structure of supercritical water, at different thermodynamic states, for densities rang ing from 0.2 to 0.7 g.cm(-3), studied by neutron scattering. The experiment al partial pair correlation functions g(OH)(r), g(HH)(r) and g(OO)(r) are c ompared with the results of molecular dynamics simulations using the (SPCE) model potential for water. The results confirm that hydrogen bonding is st ill present. in dense supercritical water and are in good agreement with da ta obtained by NMR and Raman spectroscopies. (C) 2001 Elsevier Science B.V.
