The IR spectrum of the azo derivatives shows broad OH absorptions centered around 3400 cm-1 due to intramolecular hydrogen bonding between those groups and N atoms of the azo group. 18-21 This band is ...

Glycine (Gly) is used as a model system to evaluate the ability of ultrafast two-dimensional infrared (2D-IR) spectroscopy to detect and quantify the low-molecular-weight proteinaceous components of ...

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 show that 2D IR ...
