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 …

We review two-dimensional infrared (2D IR) spectroscopy of the amide I protein backbone
vibration. Amide I modes are known for secondary structural sensitivity derived from their …

The first step toward understanding most of the chemical and biological processes in
condensed phases is to accurately describe solute− solvent interaction energy and to …

Numerous linear and non-linear spectroscopic techniques have been developed to
elucidate structural and functional information of complex systems ranging from natural …

We investigate the sensitivity of femtosecond Fourier transform two-dimensional infrared
spectroscopy to protein secondary structure with a study of antiparallel β-sheets. The results …

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 …
