ELECTRON AFFINITIES DETERMINED USING THE MAGNETRON, ALKALI METAL BEAM, PHOTON, AND COLLISIONAL IONIZATION METHODS... 

Recent reviews on alkali metal beam studies, theoretical and experimental determinations of electron affinities using photon methods, and atomic electron affinities and an Internet source for electron affinities all give compilations [113-117]. The evaluation of molecular electron affinities is a major objective of this book. 

The reaction AB —) I hv AB e is the basis of photoelectron spectroscopy and photodetachment methods. Many precise and accurate ionization potentials of molecules have been obtained by studying the photoionization of neutral molecules. The same principles apply to the photon methods for determining electron affinities, except that negative ions are studied. The electron affinities of over 1,000 atoms, radicals, clusters, and small molecules have been determined using...
