Rotational Structure in Molecular Infrared Spectra, Second Edition, fills the gap between these complex topics and the most elementary methods in the field of rotational structure in the infrared spectra of gaseous molecules. Combining foundational theoretical information with advanced applications, this book is a useful guide for all those involved in the application of molecular spectroscopic techniques and the interpretation of vibration-rotation spectra. Interpreting vibration-rotation spectra is an important skill in many scientific disciplines, ranging from nanochemistry to planetary research, hence this book is an ideal resource.
