SUMMARY:Multidimensional spectroscopy of complex chemical systems: Usi
ng nonlinearity to isolate signals\, Chaos & Complex Systems Seminar\,
Blaise Thompson\, UW Department of Chemistry
DESCRIPTION:Chemical systems are typically composed of many individual
components. Each component may be unique. Furthermore\, each componen
t 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 compl
ex\, coupled systems.
\n
\nSpectroscopy uses the interaction o
f light and matter to measure chemical energies. Multidimensional spec
troscopy (MDS) capitalizes on nonlinearities in this interaction to pe
er into higher-order properties of the chemical system. These higher-o
rder signals reveal coupling parameters of the system. In this way\, s
cientists can use MDS to isolate unique properties of chemical systems
that cannot be measured through other means. Ultrafast dynamics can a
lso be tracked.
\n
\nThis presentation will introduce the basi
c concepts of MDS. An intuitive description of the technique will be p
resented. Practical advantages will be highlighted.
