Atomic and Molecular Spectroscopy is a wide-ranging review of modern spectroscopic techniques such as X-ray, photoelectron, optical, and laser spectroscopy, and radiofrequency and microwave techniques. On the fundamental side it focuses on physical principles and the impact of spectroscopy on our understanding of the building blocks of matter. In the area of applications particular attention is given to those in chemical analysis, photochemistry, surface characterization, environmental and medical diagnostics, remote sensing and astrophysics. The audience is third or fourth year university students as well as graduate students, for whom the book serves as a course text. Research scientists and engineers can also use the book to get an overview of the latest developments in the field with ample reference to original and overview papers as well as the relevant books in various fields. The new edition provides the reader with an update on laser cooling and trapping, Bose-Einstein condensation, ultra-fast spectroscopy, high-power laser/matter interaction, satellite-based astronomy and spectroscopic aspects of laser medicine, plus recent references.
