Rotational Structure in Molecular Infrared Spectra

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.

Includes new content on the interaction of rotation and nuclear electric quadrupoles, coupled and uncoupled nuclei, and internal rotation from the high-barrier basis limitProvides updated tables and figures throughout to support the knowledge outlined in the textOutlines different paths through the text to help readers from different backgrounds explore the most appropriate content for their needs
