The success of EMS in wave-function mapping and elucidating the electronic structure of atoms led to its rapid application as a probe of the valence electronic structure of molecules. Methane was the first molecule studied,209 the Flinders group using the same noncoplanar symmetric spectrometer employed in their earlier study of argon.64 Since those first studies about 100 molecules have been studied using EMS (e.g., see Leung’s bibliographies179, 210), and it has become one of the premier tools in the study of the electronic structure of molecules, particularly of the valence shell.
