Abstract
An experiment is described to study temporal variations of the hydrogen bond length in liquid water. The principles of this laser spectroscopic experiment are explained first. The construction of a laser source generating 150 fs pulses in the 2.5-4.4 μm spectral region is detailed next. The theoretical analysis is proposed in terms of statistical mechanics of nonlinear optical processes. A new spectral effect is reported, the pump-probe delay dependent solvatochromic shift of the OH band. It is shown how this effect can be exploited to "photograph" the dynamics of the OH...O bonds in real time.
