Abstract

The chapter focuses on chemical applications of microwaves. The chapter begins with the discussion on microwave absorption spectroscopy. This section is limited to molecular gases. Absorption by atomic gases is extremely rare. For a molecular gas to absorb microwave radiation, three conditions must be met. The chapter offers a description of these conditions. The chapter also discusses nuclear magnetic resonance (NMR) spectroscopy. The proton and many kinds of nuclei behave as if they spin about an internal axis. This spin is characterized in part by a nuclear spin quantum number, I. Electron spin resonance spectroscopy has also been explored. The electron behaves as if it spins about an internal axis. This spin is characterized in part by a spin quantum number, s, the only allowed value of which is ½. Electron spin systems relax by essentially the same mechanisms as nuclear spin systems, although the rate is in general much faster because of the smaller mass of the electron.
