Ultrafast multiple-mode multiple-dimensional vibrational spectroscopy

Ultrafast multiple-dimensional vibrational spectroscopy has been extensively applied to studies of molecular structures and dynamics in condensed phases. Along with the developments of new laser sources and new concepts, increasing improvements and applications of this technique have brought the understanding of molecular systems to a new level. In this review, we first briefly introduce the basic concepts, experimental setups and applications of the technique. The most recent progresses in applying vibrational energy transfers to determine intermolecular distances and vibrational couplings to determine three dimensional molecular conformations with our high power multiple-mode multiple-dimensional vibrational spectroscopy are then introduced in more details.
