"Coherent Multidimensional Spectroscopy of Gas Phase Molecules"

Abstract: Gas phase spectroscopy has a long and rich history of producing detailed information on the structure and behavior of molecules.  Recently, the need to develop new gas phase techniques have been driven by problems such as climate change and opportunities such as the search for possible life beyond earth.  These kinds of applications can pose challenges for existing 1D spectroscopic methods.  This talk describes how multidimensional spectroscopy can provide solutions to some of these challenges.  Multidimensional spectra of gas phase systems contain unique, detailed multidimensional patterns that can provide more information about molecular structure and behavior.  This talk will describe the kinds of patterns that are formed, new methods for creating and analyzing them, and what we can learn from them.
