Dynamique femtoseconde de la liaison hydrogène

Abstract : A pump-probe experiment is described to study femtosecond dynamics of hydrogen bonds in liquid water. The key element of the experimental setup is a laser source emitting 150 fs pulses in the 2.5-4.4 urn spectral region, at 10 nJ power level. The OH-stretching band is recorded for different excitation frequencies and different pump-probe delay times. Time-dependent solvatochromic shifts are observed and are interpreted with the help of statistical mechanics of nonlinear optical processes. Using these spectral data, the OH -O motions are "photographed" in real time. Cop. EDP Sciences.
