Abstract:

In recent years, ultrafast multiple-dimensional vibrational spectroscopy has been widely applied to studies of molecular structures and ultrafast dynamics in various condensed phases, and is expected to become a new generation of routine analytical tool for determining microstructures and ultrafast behaviors in molecular systems. In this review, we introduce in detail a method of determining three-dimensional (3D) molecular conformations with ultrafast multiple-dimensional vibrational spectroscopy. The introduction of our research follows two directions:(1) obtaining relative spatial orientations of different groups in a molecular system and finally determining molecular conformations by measuring cross angles of vibrational transition dipole moments; and (2) exploring the nature of vibrational energy transfers and determining molecular distances with experimentally measured vibrational energy transfer rates.

Key words: Multiple-dimensional vibrational spectroscopy, Ultrafast spectroscopy, 2D infrared spectroscopy, Molecular conformation, Vibrational energy transfer
