IAU Symposium Proceedings of the International Astronomical Union IAU Symposium No. 280 IAU Symposium 30 May-3 June 2011 Astrochemistry, the study of molecules and their chemistry in astrophysical objects throughout the Universe, is experiencing a true Toledo, Spain golden age. Astronomical observations of molecules are crucial 280 in contributing to our understanding of the physical conditions in many different astrophysical environments, from the Solar System and The Molecular extrasolar planets to stars, interstellar clouds and galaxies. Concurrently, 30 May - 3 June 280 30 May - 3 June 2011 The Molecular laboratory experiments and theoretical studies can provide basic 2011 information about the often exotic chemical processes taking place Toledo, Spain in the Universe. IAU Symposium 280 contains outstanding reviews Toledo, Spain Universe Universe on the advances in observational, laboratory, theoretical and modelling studies, carried out by leading scientists worldwide. This volume provides researchers and graduate students with an indispensable account of the current state of astrochemistry, its recent successes and the immense possibilities of this fascinating field for future growth. Proceedings of the International Astronomical Union Editor in Chief: Prof. Thierry Montmerle This series contains the proceedings of major scientific meetings held by the International Astronomical Union. Each volume contains a series of articles on a topic of current interest in astronomy, giving a timely overview of research in the field. With contributions by leading scientists, The Molecular these books are at a level suitable for research astronomers and graduate students.

The Orion Nebula is known to be one of the most prolific chemical factories in space, although the full extent of its chemistry and the pathways for molecule formation are not well understood. This extremely rich spectrum, obtained with the HIFI spectrometer in January 2010, covers the range 1.059 to 1.115 THz. Among the molecules that can be identified in this spectrum (marked on the cor- responding lines) are water, carbon monoxide, formaldehyde, methanol, dimethyl ether, hydrogen cyanide, sulphur oxide, sulphur dioxide and their isotope ana- logues. It is expected that many new organic molecules will also be identified. Identification of the many spectral features visible in the Orion spectrum with transitions of particular molecular species requires sophisticated molecular spec- troscopy databases, which collect the results from many years of theoretical and laboratory spectroscopy work. HERSCHEL is an ESA space observatory with science instruments provided by European-led Principal Investigator consortia, with important participation from NASA. The high resolution spectrometer HIFI was designed and built by a nationally-funded consortium led by SRON Netherlands Institute for Space Re- search. The consortium includes institutes from France, Germany, USA, Canada, Ireland, Italy, Poland, Russia, Spain, Sweden, Switzerland, and Taiwan.
