A PHOTOELECTRON STUDY OF THE INNER VALENCE MOLECULAR-ORBITALS OF N2O

Photoelectron spectra are reported for the inner and outer valence regions of N#2#O for several photon energies up to 120 eV. The outer valence region is characterized by four well resolved bands which can be assigned to ionisation from specific molecular orbitals. In contrast, the inner valence region displays a complex structure, composed of many overlapping lines, extending to a binding energy of approximately 45 eV. The experimental data are compared with theoretical calculations and with a spectrum recorded using X-ray excitation. Several of the features observed in the inner valence region can be interpreted with the aid of theoretical predictions. © 1990.
