Giving infrared spectroscopy a boost: New methods for studying interfaces, chirality, vibrational coupling across the spectrum, and proton transfer reactions
Seminar | November 7 | 4-5 p.m. | 120 Latimer Hall
Mid-infrared (IR) spectroscopy directly interrogates the chemical bonds molecules are composed of through their vibrational frequencies and thus offers a direct and local probe of molecular structure and nuclear motion. However, ultrafast IR spectroscopy is very challenging and thus heavily technology driven. Progress is driven by technical advances and the development of new laser sources and techniques that shed new light on existing problems, resolve controversies, and can lead to the discovery of new and unexpected phenomena. We are pushing the envelope of ultrafast mid-IR spectroscopic methods to probe the structure and dynamics at surface and in bulk systems, and further applying them to a series of novel systems. This includes new methods for studying chiral water structures in biological settings, surface-bound catalysts, and the ultrafast vibrational dynamics and proton transfer within strongly hydrogen-bonded systems.
Light refreshments will be served at 3:50 at The Coffee Lab
