Transient 2D-IR spectroscopy of thiopeptide isomerization


Cervetto, V; Hamm, P; Helbing, J (2008). Transient 2D-IR spectroscopy of thiopeptide isomerization. Journal of Physical Chemistry. B, 112(28):8398-8405.

Abstract

Transient 2D-IR spectra have been recorded during the photoreaction of the thioxopeptide Boc-Ala-Gly(=S)-Ala-Aib-OMe. We demonstrate the potential of transient 2D-IR spectroscopy to resolve vibrational bands hidden in conventional pump−probe spectra. Different types of transient cross-peak signals are observed, and their information content is discussed by comparison with model spectra.
