X-Ray Photoelectron Spectra of NaNO₂ and KNO₂

Abstract

X-ray photoelectron spectra of NaNO₂ and KNO₂ are investigated. The structure of the valence-electron spectra is compared with the molecular-orbital (MO) calculations of the NO₂⁻ ion and the energy-band calculation of NaNO₂ crystal. The band picture may interpret the structure of the observed spectra better than the MO-scheme. The energies of the inner core lines are tabulated as well as those of the main peaks in the valence-electron spectra.
