title: [Relaxation of liquid water states with altered stoichiometry].
abstract: The integral parameter of the physical state of liquid water, its stoichiometry composition, is considered. This factor takes into account that the substance of liquid water contains oxygen and hydrogen atoms in the proportion other than the ideal 2:1 ratio characteristic of a separate water molecule. The stoichiometry index χ of water--a deviation from the ideal ratio--is shown to be an independent metastable variable that determines equilibrium concentrations of the oxygen-hydrogen molecules. The optical method for measuring χ is suggested, and a laser interferometer is described that is capable of measuring the stoichiometry index to an accuracy of 10(-5). Possible applications of the instrument in biophysics of water systems are discussed.
