A gentle reminder. Dear colleagues, Please join us next Monday for a seminar sponsored by the Atomic and Molecular Physics Division, Harvard-Smithsonian Center for Astrophysics. Complete schedule at http://www.cfa.harvard.edu/amp/events.html *** Please let me know if you want to meet with our speaker. *** 11:00 AM Monday, March 4, 2013 Phillips Auditorium Center for Astrophysics 60 Garden St, Cambridge, MA Author: Dr. Timothy J. Lee, Chief Space Science & Astrobiology Division NASA Ames Research Center Title : Using Theory and Experiment to Compute Highly Accurate Line Lists for Stable Molecules, and Purely Ab Initio Theory to Compute Accurate Limited Line Lists for Transient Molecules Abstract Theoretical chemists have been computing vibrational and rovibrational spectra of small molecules for more than 40 years, but over the last decade the interest in this application has grown significantly. The increased interest in computing accurate rotational and rovibrational spectra for small molecules could not come at a better time, as NASA and ESA have begun to acquire a mountain of high-resolution spectra from the Herschel mission, and soon will from the SOFIA and JWST missions. In addition, the ground-based telescope, ALMA, will begin to acquire high-resolution spectra in the same time frame. Hence the need for highly accurate line lists for many small molecules, including their minor isotopologues, will only continue to increase. I will present the latest developments from our group on using the "Best Theory + High-resolution Experimental Data" strategy to compute highly accurate rotational and rovibrational spectra for small molecules, including NH3, CO2, and SO2. I will also present the latest work from our group in producing limited line lists and spectroscopic constants for small molecules thought to exist in various astrophysical environments, but for which there is either limited or no high-resolution experimental data available.
