Direct Evidence from Gas-Phase Atomic Spectra for an Unscreened Intra-Atomic Origin of Outer-Core Multiplet Splittings in Solid Manganese Compounds.

摘要

In this Letter, we compare core-level photoelectron spectra of a free transition metal atom with corresponding spectra from solid compounds for the first time in an attempt to resolve more precisely the exact nature of the multiplet splittings and final-state extra atomic screening processes involved. We first discuss prior theoretical models for such effects and then consider our experimental data in this context. Keywords: Molecular chemistry, Reprints. (JES)
