Chaos & Complex Systems Seminar
Multidimensional spectroscopy of complex chemical systems: Using nonlinearity to isolate signals
Date: Tuesday, November 7th
Time: 12:05 pm - 1:00 pm
Place: 4274 Chamberlin (refreshments will be served)
Speaker: Blaise Thompson, UW Department of Chemistry
Abstract: Chemical systems are typically composed of many individual components. Each component may be unique. Furthermore, each component may experience a different chemical environment. At room temperature, these environments evolve on ultrafast time scales. Scientists need specialized techniques to understand what is happening in these complex, coupled systems.

Spectroscopy uses the interaction of light and matter to measure chemical energies. Multidimensional spectroscopy (MDS) capitalizes on nonlinearities in this interaction to peer into higher-order properties of the chemical system. These higher-order signals reveal coupling parameters of the system. In this way, scientists can use MDS to isolate unique properties of chemical systems that cannot be measured through other means. Ultrafast dynamics can also be tracked.

This presentation will introduce the basic concepts of MDS. An intuitive description of the technique will be presented. Practical advantages will be highlighted.
