The Role of Orientation and Alignment in Molecular Processes

Part of the Physics of Atoms and Molecules book series (PAMO)


In typical spectroscopic or collision experiments molecules rotate freely and isotropic averaging of the process considerably reduces the amount of information on the interactions. In recent years several methods have therefore been developed to produce anisotropic distributions of molecular angular momenta: for example, focusing by external electric fields, optical pumping by polarized laser excitation, or rotational cooling in supersonic expansions (see, for example, the reviews by Herschbach, 1992; Friedrich et al., 1991; Scoles, 1988).
