Vibrational spectroscopy is an essential tool in chemical analyses, biological assays, and
studies of functional materials. Over the past decade, various coherent nonlinear vibrational …

One of the great dream experiments in Science is to directly observe atomic motions as they
occur. Femtosecond electron diffraction provided the first'light'of sufficient intensity to …

Water is, of course, a fascinating and important substance. For such a simple molecule, its
condensed phase properties are surprisingly complex. Here we might mention the many …

Because of strong hydrogen bonding in liquid water, intermolecular interactions between
water molecules are highly delocalized. Previous two-dimensional infrared spectroscopy …

The advent of laser-based sources of ultrafast infrared pulses has extended the study of very
fast molecular dynamics to the observation of processes manifested through their effects on …

Water's ability to donate and accept hydrogen bonds leads to unique and complex collective
dynamical phenomena associated with its hydrogen-bond network. It is appreciated that the …

Good vibrations: The vibrational response of complex molecules to sequences of infrared
pulses provides novel femtosecond snapshots of their structure and dynamics. This …

Infrared spectroscopy of the water OH stretch provides a sensitive probe of the local
hydrogen-bonding structure and dynamics of water molecules. Previously, we have utilized …

We discuss a novel approach for nonlinear two-dimensional (2D) spectroscopy in the
terahertz (THz) frequency range which is based on a collinear interaction geometry of a …

We study theoretically the steady-state and ultrafast vibrational spectroscopy, in the OD-
stretch region, of dilute HOD in aqueous solutions of sodium bromide. Based on electronic …
