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

2 1 Introduction the most salient points are just that a molecule can exist in a variety of states
depending on how its electrons are distributed among a set of molecular orbitals, and that …

The involvement of chemical exchange in 2D IR heterodyne echo spectroscopy is
characterized through the hydrogen-bond exchange between CH3OH and the CN of …

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 …

The principal contributions to the anharmonic coupling of amide vibrations are explored with
the objective of comparing recent experiments with density functional theory and evaluating …

Dual-frequency 2D IR heterodyned photon echo experiments with independently tunable
mid-IR pulses are presented. Two-dimensional IR spectra acquired using three pulses in a …

The CN vibrations of two aromatic nitriles, cinnamonitrile, PhCHCH–CN and benzonitrile,
PhCN, representative of components of common enzyme inhibitors, are examined by two …

Hydrogen bonds are ubiquitous and of fundamental relevance in nature. Representing a
local attractive interaction between a hydrogen donor and an adjacent acceptor group, they …

The equilibrium dynamics of the acetyl and amino amide-I groups of the alanine dipeptide
were examined separately using 13C isotopic selection and 2D IR. The population …

Dual-frequency 2D IR heterodyne photon-echo spectroscopy of C⋮ N and CO stretching
vibrational modes in 2-cyanocoumarin is reported. We have shown that the interaction …
