Tuesday, 11:00 am Room 1315 September 6, 2016 Chemistry Building Professor Elad Harel Department of Chemistry Northwestern University Host: Professor Martin Zanni Refreshments will be available prior to the seminar at 10:45 a.m. outside room 1315 Graduate Students can meet with the speaker in Room 8305F at 1:00 pm Ultrafast Electronic-Raman Spectroscopy and Single Particle Imaging of Artificial and Natural Light-Harvesting Systems Our lab is developing new approaches to study how charge and energy move in complex molecular systems at the extremes of time and space. Specifically, we have developed 4D Electronic-Raman spectroscopy and sub-diffraction transient- absorption microscopy, methods that are uniquely sensitive to electron-phonon- vibrational interactions. We highlight the use of these complimentary techniques for examining a diverse array of systems from pigment-protein complexes to hybrid lead halide perovskites.
