Identification of the weak features in N 1s near-edge X-ray absorption fine structure of N 2O multilayer
Abstract
The multiple-scattering cluster method has been employed to calculate N 1s near-edge X-ray absorption fine structure (NEXAFS) of N 2O single molecule and N 2O multilayer. It has been shown that the complicated weak features in the NEXAFS of N 2O multilayer are attributed to four σ resonances and two weak features. Two weak features are attributed to the interaction between N 2O molecular layers. The result of the self-consistent field (SCF) DV-Xα calculation of N 2O multilayer has confirmed above conclusion. The analysis of N 2O numbers in molecular chain shows the feature σ1 is weakened due to the interaction between the intermediate photoelectron and the potential of the ionic molecules.
