Ultrafast Vibrational Spectroscopy of Inhomogeneous Energetic Materials and Energetic Interfaces

摘要

The goal of this project is the development of a fundamental understanding of nanocomposite energetic materials and fast mechanical processes at a molecular level. We are attacking these difficult problems using three parallel approaches. (1) Laser flash-heating of nanoenergetic materials combined with optical diagnostic techniques; (2) Ultrafast laser shock compression of solids combined with vibrational spectroscopy; (3) Multidimensional vibrational spectroscopy of liquids to study the flow of vibrational energy.
