Molecules and Radiation

This unified treatment introduces upper-level undergraduates and graduate students to the concepts and methods of modern molecular spectroscopy and their applications to quantum electronics lasers and related optical phenomena.Starting with a review of the prerequisite quantum mechanical background the text examines atomic spectra and diatomic molecules including the rotation and vibration of diatomic molecules and their electronic spectra. A discussion of rudimentary group theory advances to considerations of the rotational spectra of polyatomic molecules and their vibrational and electronic spectra; molecular beams masers and lasers; and a variety of forms of spectroscopy including optical resonance spectroscopy coherent transient spectroscopy multiple-photon spectroscopy and spectroscopy beyond molecular constants. The text concludes with a series of useful appendixes.
