Proceedings of the International Astronomical Union IAU Symposium No. 297 IAU Symposium IAU Symposium 20–24 May 2013 This volume describes the current state of the art in research aimed at unraveling the carriers of the enigmatic diffuse interstellar bands 297 Noordwijkerhout, (DIBs). The DIBs are a set of hundreds of absorption bands that are The Netherlands seen from the near-ultraviolet to near-infrared wavelengths. Their interstellar origin is well established, but the precise chemical identity of the DIB carriers remains to date one of the greatest 20–24 May 2013 297 20–24 May 2013 The Diffuse unsolved mysteries in astronomical spectroscopy. These Noordwijkerhout, The Diffuse proceedings of IAU Symposium 297 include more than 70 Noordwijkerhout, contributions that cover a wide range of topics in observational The Netherlands Interstellar astronomy and astrophysics; laboratory astrophysics and The Netherlands Interstellar Bands spectroscopy; astrochemistry; and theoretical, experimental and computational chemistry. This interdisciplinary overview contains Bands all the required background material to make the volume an ideal starting point for researchers and graduate students to learn about the various aspects of DIBs and related topics. Proceedings of the International Astronomical Union Editor in Chief: Prof. Thierry Montmerle This series contains the proceedings of major scientifi c 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 fi eld. With contributions by leading scientists, these books are at a level The Diffuse suitable for research astronomers and graduate students. Interstellar Edited by Bands Cami Cox Jan Cami Nick L.J.
