Prof. Markus B. Raschke raschke@chem.washington.edu
office: BAG 227, 206-543-2906

Interest in linear and nonlinear optical spectroscopy at surfaces and of nanostructures. For simultaneous spatial information we explore new routes for ultrahigh resolution optical imaging far beyond the diffraction limit. Topics include single molecule spectroscopy, surface photochemistry, molecular plasmonics as well as surface electron dynamics and electron-phonon interaction.
