Abstract
Previously published X-ray emission spectra (Mg Kβ 1,3; MgL 2,3M and OKα) from magnesium oxide are aligned on a common energy scale using atomic orbital ionisation energies determined by X-ray photoelectron spectroscopy. All three spectra show two principal components which derive from the same two bands of molecular orbitals. The two components of both magnesium spectra have equal intensity; in the oxygen spectrum the high energy peak is the most intense: these observations are rationalised using a simple molecular orbital model based on the MgO 6 10−unit. It is necessary to consider the interactions of this unit with further magnesium and oxygen atoms and also π -type perturbations between Mg—O σ bonds in order to explain the structure of the observed emission spectra (but there is no recourse to forbidden 3 d → 1 s transitions).
