Molecular beam magnetic and electric resonance

Molecular beam techniques are now very well estabhshed, for the study of both spectroscopy and fundamental reactive and non-reactive scattering dynamics. They have been described in numerous review articles and books, so in this chapter we content ourselves with details sufficient to imderstand the beautifiil experiments which have been performed, but insufficient for those readers with ambitions to enter the field experimentally. For those requiring more details, the 1988 and 1992 two-volume collection of speciahst articles edited by Scoles [1] constitutes an excellent summary, with many references to the original literature. 

Many of the classic studies we will describe were carried out more than sixty years ago, when the available radioffequency and high-vacuum technology was primitive compared with that enjoyed now, at the beginning of the new millennium. We will describe the original experiments faithfully, whilst also giving an outline of how such studies might be performed today. At the same time we will also attempt to achieve
