Two-dimensional (2D) optical spectroscopy utilizing multiple ultrafast coherent laser pulses
in the infrared or UV-vis frequency range has been used to study protein structure and …

Hydrogen bonding represents one of the fundamental types of chemical bonding and
underlies the structure of a large variety of molecular systems, among them liquids …

Suggested mechanisms for proton mobility are confronted with experimental findings and
quantum mechanical calculations, indicating that no model is consistent with the existing …

In a series of molecular dynamics calculations we simulate the dynamics of forming and
breaking a hydrogen bond in liquid water at room temperature. We show that this dynamics …

The unique properties of water in the supercooled (metastable) state are not fully
understood. In particular, the effects of solutes and mechanical pressure on the kinetics of …

We investigated rearrangements of the hydrogen-bond network in water by measuring
fluctuations in the OH-stretching frequency of HOD in liquid D2O with femtosecond infrared …

It is well known that the solvent plays a critical role in ultrafast electron-transfer reactions.
However, solvent reorganization occurs on multiple length scales, and selectively …

We report the frequency-dependent optical constants, n (ν) and α (ν), or, equivalently, the
complex permittivity ε (ω)= ε '(ω)− iε ''(ω), over the frequency range from 2 to 50 cm-1 for …

Water is in many aspects a remarkable liquid. Apart from its importance in biological
processes and the extended use in chemistry as solvent, the exceptional properties of liquid …

Many of the unusual properties of liquid water are attributed to its unique structure,
comprised of a random and fluctuating three-dimensional network of hydrogen bonds that …
