Abstract
X-ray absorption spectroscopy provides direct evidence for localized valence electrons in , , and dimer cations. Bonding in these transition-metal molecules is predominantly mediated by electrons. This behavior is markedly different from other transition-metal dimers with open subshells and can be ascribed to the highly stable configuration of the subshell in chromium and manganese atoms and ions. In , , and , electron localization indicates local high spin states.
