High Resolution Spectroscopy discusses the underlying concepts in the different branches of spectroscopy, especially in high resolution spectroscopy. The coverage of the book includes basic principles such as the quantization of energy, as well as the interaction of electromagnetic radiation with atoms and molecules; general experimental methods and features of instrumentation; and microwave, millimeter wave, and lamb dip spectroscopy. Also covered in the book are subjects such as the principles behind rotational spectroscopy; diatomic and polyatomic molecules in vibrational spectroscopy; and ...
