Adaptive femtosecond pulse shaping, a key experimental methodology used, has immense potential to control electronically, structurally, and reactively complex systems. However, its maturation into a tool for understanding as well as control will benefit tremendously from a multifaceted research program combining molecular design, synthesis, theory, and spectroscopy on all relevant time scales with and without control. In this talk I will highlight recent efforts to interrogate and control photochemical pathways in novel coordination complexes wherein internal motions are expected to modulate the rate of a photoinduced electron transfer reaction. We have hypothesized that photochemical control may be possible if adaptively shaped laser fields can manipulate these motions. In addition I will introduce recent experiments designed to test whether multiple exciton generation yields in lead-salt quantum dots is sensitive to the phase characteristics of an incident laser field and whether this can help us explore  mechanisms for multiple carrier generation.\n\u003C\/p\u003E\n\u003Cp\u003EFor more information contact \u003Ca href=\u0022mailto:david.sherrill@chemistry.gatech.edu\u0022\u003EProf. David Sherrill\u003C\/a\u003E (404-894-4037).\u003C\/p\u003E","summary":null,"format":"limited_html"}],"field_subtitle":"","field_summary":[{"value":"Prof. Niels Damrauer,University of Colorado, Boulder\n\nElements of photochemical control through manipulation of structure and phase-shaping of laser fields.","format":"limited_html"}],"field_summary_sentence":[{"value":"Prof. Niels Damrauer, Univ of Colorado, Boulder"}],"uid":"27275","created_gmt":"2009-01-12 01:00:00","changed_gmt":"2016-10-08 01:57:16","author":"Shirley Tomes","boilerplate_text":"","field_publication":"","field_article_url":"","field_event_time":{"event_time_start":"2009-03-31T16:00:00-04:00","event_time_end":"2009-03-31T17:00:00-04:00","event_time_end_last":"2009-03-31T17:00:00-04:00","gmt_time_start":"2009-03-31 20:00:00","gmt_time_end":"2009-03-31 21:00:00","gmt_time_end_last":"2009-03-31 21:00:00","rrule":null,"timezone":"America\/New_York"},"extras":[],"related_links":[{"url":"http:\/\/www.colorado.edu\/chem\/damrauerlab\/","title":"Prof. Niels Damrauer, University of Colorado at Boulder"}],"groups":[{"id":"85951","name":"School of Chemistry and Biochemistry"}],"categories":[],"keywords":[{"id":"1809","name":"physical chemistry"}],"core_research_areas":[],"news_room_topics":[],"event_categories":[{"id":"1795","name":"Seminar\/Lecture\/Colloquium"}],"invited_audience":[],"affiliations":[],"classification":[],"areas_of_expertise":[],"news_and_recent_appearances":[],"phone":[],"contact":[{"value":"\u003Cstrong\u003EShirley Tomes\u003C\/strong\u003E\u003Cbr \/\u003EChemistry \u0026amp; Biochemistry\u003Cbr \/\u003E\u003Ca href=\u0022http:\/\/www.gatech.edu\/contact\/index.html?id=st81\u0022\u003EContact Shirley Tomes\u003C\/a\u003E\u003Cbr \/\u003E\u003Cstrong\u003E404-894-0591\u003C\/strong\u003E","format":"limited_html"}],"email":[],"slides":[],"orientation":[],"userdata":""}}}
