Infrared Vibration—Rotation Spectroscopy: From Free Radicals to the Infrared Sky contains new experimental and theoretical methods on the high resolution infrared spectroscopy of small molecules. The book is divided into three parts. Features covered in the first part include:

• Calculations of the vibration-rotation energy levels of rigid and non-rigid molecules
• Calculations of the intensities of vibration-rotation transitions
• Introduction to linear and non-linear molecular spectroscopy
• Use of interferemetric and laser spectrometers for measuring infrared spectra.

The second part presents a detailed treatment of the analysis of the high resolution vibration—rotation spectra of linear, quasilinear, symmetric rotor and asymmetric rotor molecules. The following topics of current interest are examined in depth in the final part of the book:

• Electric and magnetic resonance spectroscopy
• Spectroscopy of transient species, free radicals and ions, and Van der Waals clusters
• Atmospheric and astrophysical spectroscopy, including the spectroscopy of the atmosphere of the Earth and nearby planets, cool stars and molecules in the interstellar medium

This comprehensive book is an ideal reference book for researchers in the field of spectroscopy and physical chemistry, and of atmospheric science and infrared astronomy. It is also recommended as a text book for graduate students in molecular spectroscopy.
