Abstract
Anomalously large fluctuations are experimentally found for the gravitational center of the OH band envelope of the Raman scattering of 10-ns pulses in water. Upon sensing of water with 15-ps pulses, OH band fluctuations multiply increase, which indicates existence of nonequilibrium processes at the finite lifetime of hydrogen bonds. Spectral density instabilities of OH oscillator states are analyzed using the model of fluctuations of the number of hydrogen bonds due to assumed formation/destruction of different-sized structural complexes in water.
