TL;DR: In this paper, a femtosecond pump probe and dynamic hole burning experiments were used to examine the ultrafast response of the modes in the 1600−1700 cm-1 region (the so-called amide I modes) of N-methylacetamide (NMA) and three small globular peptides, apamin, scyllatoxin, and bovine pancreatic trypsin inhibitor (BPTI).

TL;DR: In this paper, the essential concepts of 2D IR spectroscopy step-by-step to build an intuitive and in-depth understanding of the method are presented. But they do not cover the design considerations for implementing the methods in the laboratory.

TL;DR: In this paper, the central backbone structure of trialanine in aqueous solution is investigated using polarization sensitive two-dimensional (2D) vibrational spectroscopy on the amide I mode.

TL;DR: A form of two-dimensional vibrational spectroscopy, which uses two ultrafast IR laser pulses, is used to examine the structure of a cyclic penta-peptide in solution and measures the coupling between the different amide groups in the structure.

TL;DR: In this paper, the vibrational cooling of azobenzene after photoisomerization was investigated by time resolved IR spectroscopy with femtosecond time resolution, and the experimental data were discussed in terms of a simple theoretical model which was derived in order to account for the off-diagonal anharmonicity between the investigated highfrequency modes and the bath of the remaining low-frequency modes in polyatomic molecules.
