Ultrafast 2D-IR spectroscopy method and applications

摘要

Since the first experiment was performednearly a decade ago,' ultrafast two-dimen-sional infrared (2D-IR) spectroscopy hasemerged as an exciting non-linear ultra-fast laser technique for probing molecularstructure and solute–solvent interactiondynamics in a range of systems of chem-ical and biological relevance. Additionally,the unique combination of structuralinformation and ultrafast time resolutionallows 2D-IR spectroscopy to probe non-equilibrium and even reacting systems,effectively making real-time movies ofmolecular processes. This article providesa brief introduction to the experimentalmethodologies behind ultrafast 2D-IRspectroscopy before using applicationsto illustrate the additional informationafforded by this new approach.
