Atomic and Molecular Spectroscopy is a wide-ranging review of modern spectroscopic techniques such as X-ray, photoelectron, optical and laser spectroscopy, as well as 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, while in the area of applications particular attention is paid to chemical analysis, photochemistry, surface characterisation, environmental and medical diagnostics, remote sensing and astrophysics. The third edition also provides the reader with an update on laser cooling and trapping, Bose-Einstein condensation, ultrafast spectroscopy, high-power laser/matter interaction, satellite-based astronomy and spectroscopic aspects of laser medicine.
