Molecular line emissions offer researchers exciting opportunities to learn about the evolutionary state of the Milky Way and distant galaxies. This text provides a detailed introduction to molecular astrophysics and an array of useful techniques for observing astronomical phenomena at millimetre and submillimetre wavelengths. After discussing the theoretical underpinnings of molecular observation, the authors catalogue suitable molecular tracers for many types of astronomical regions in local and distant parts of the Universe, including cold gas reservoirs primed for the formation of new stars, regions of active star formation, giant photon-dominated regions and near active galactic nuclei. Further chapters demonstrate how to obtain useful astronomical information from raw telescope data while providing recommendations for appropriate observing strategies. Replete with maps, charts and references for further reading, Observational Molecular Astronomy will suit research astronomers and graduate students interested in broadening their skill to take advantage of the new facilities now coming online.

David A. Williams is the Emeritus Perren Professor of Astronomy at University College London. A former president of the Royal Astronomical Society (2000–2) and recipient of the RAS's Gold Medal (2009), he has led research groups in Manchester and London, and has co-authored a number of texts on astrophysics and astrochemistry. His research interests centre on astrochemistry and using molecular line emissions to describe and understand the evolution of astronomical regions.
Serena Viti is a Professor of Astrophysics at University College London. She began her career working on the spectroscopy of very cool stars but soon became interested in star formation and astrochemistry. She is the secretary of the European Astronomical Society and she routinely serves on national and international scientific panels and committees.
"This book is an excellent introduction to the field of molecular line astrophysics. Williams and Viti cover the range of astrophysical conditions that can be probed, and the most useful molecules and transitions. The expositions are lucid, and each chapter directs the reader to papers and books for further study, and to websites where up-to-date molecular data are available. Observational Molecular Astronomy will be a valuable guide to both graduate students and researchers."

"This handbook provides everything needed to understand molecular astrochemistry – it will prove useful to both observers and theorists alike. It covers all of the topics a modern researcher needs to know in order to carry out observations of molecules in space, and then to reduce and analyse those observations. It also explains all aspects of molecular spectroscopy from choosing the correct molecule to observe, to calculating the physical parameters of the object being observed. All environments are discussed, from nearby clouds to distant galaxies. I am sure that this will become the must-have handbook for all researchers in this field, from new graduate students to seasoned veterans."
