The evolution of the shape of the infrared profiles associated with the internal vibrational modes of water has been investigated. In supercritical water, at <jats:italic>T<\/jats:italic> = 380 \u00b0C and low pressure (density), in the range 25-50 bar (0.01-0.05 g\u00b7cm<jats:sup>-3<\/jats:sup>), only monomers are detected. A progressive increase of the pressure (density) from 50 to 250 bar (from 0.05 to 0.4 g\u00b7cm<jats:sup>-3<\/jats:sup>) leads to the appearance of dimers and trimers. In order to obtain information on the dynamics, we have performed incoherent quasi-elastic neutron-scattering experiments on light water for several thermodynamic states (200 &lt; <jats:italic>T<\/jats:italic> &lt; 400 \u00b0C and 184 &lt; <jats:italic>P<\/jats:italic> &lt; 400 bar) corresponding to densities ranging from 0.2 to 0.9 g\u00b7cm<jats:sup>-3<\/jats:sup>. The results have been analyzed using a jump diffusion model and the two parameters of this model, namely, \u03c4<jats:sub>0<\/jats:sub>, the residence time and <jats:italic>D<\/jats:italic>, the translational diffusion coefficient, have been determined as a function of the density.<\/jats:p>","DOI":"10.1351\/pac200476010133","type":"journal-article","created":{"date-parts":[[2007,10,13]],"date-time":"2007-10-13T17:58:54Z","timestamp":1192298334000},"page":"133-139","source":"Crossref","is-referenced-by-count":19,"title":["Supercritical water: Local order and molecular dynamics"],"prefix":"10.1515","volume":"76","author":[{"given":"T.","family":"Tassaing","sequence":"first","affiliation":[{"name":"Laboratoire de Physico-Chimie Mol\u00e9culaire, CNRS (UMR 5803), Universit\u00e9 deBordeaux I, 351 Cours de la Lib\u00e9ration, F-33405 Talence Cedex, France"}]},{"given":"Y.","family":"Danten","sequence":"additional","affiliation":[{"name":"Laboratoire de Physico-Chimie Mol\u00e9culaire, CNRS (UMR 5803), Universit\u00e9 deBordeaux I, 351 Cours de la Lib\u00e9ration, F-33405 Talence Cedex, France"}]},{"given":"M.","family":"Besnard","sequence":"additional","affiliation":[{"name":"Laboratoire de Physico-Chimie Mol\u00e9culaire, CNRS (UMR 5803), Universit\u00e9 deBordeaux I, 351 Cours de la Lib\u00e9ration, F-33405 Talence Cedex, France"}]}],"member":"374","published-online":{"date-parts":[[2009,1,1]]},"container-title":["Pure and Applied Chemistry"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.degruyter.com\/view\/journals\/pac\/76\/1\/article-p133.xml","content-type":"text\/html","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/www.degruyter.com\/document\/doi\/10.1351\/pac200476010133\/xml","content-type":"application\/xml","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/www.degruyter.com\/document\/doi\/10.1351\/pac200476010133\/pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2022,3,5]],"date-time":"2022-03-05T18:50:03Z","timestamp":1646506203000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.degruyter.com\/document\/doi\/10.1351\/pac200476010133\/html"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2004,1,1]]},"references-count":0,"journal-issue":{"issue":"1","published-online":{"date-parts":[[2009,1,1]]},"published-print":{"date-parts":[[2004,1,1]]}},"alternative-id":["10.1351\/pac200476010133"],"URL":"https:\/\/doi.org\/10.1351\/pac200476010133","relation":{},"ISSN":["1365-3075","0033-4545"],"issn-type":[{"value":"1365-3075","type":"electronic"},{"value":"0033-4545","type":"print"}],"subject":[],"published":{"date-parts":[[2004,1,1]]}}}
