Pass Energy and Resolution
Spectral pass energy affects resolution and signal
Photoionisation Cross Sections
Photoionisation cross sections influence orbital signal as a function of excitation energy
The Auger, or Auger-Meitner, Process and Auger Peaks
Auger emissions are a secondary electron process
Coster-Kronig
Coster-Kronig transitions cause unequal broadening in spin-orbit doublets
Peak Asymmetry in Conducting Materials
Conductive materials may present asymmetric photoemission peaks
Plasmon Loss
Plasmon losses must be carefully evaluated to avoid misidentification
Multiplet splitting of s-orbitals in first row transition metals
Rare multiplet splitting of S-orbitals may yield additional insights into chemical environments
Multiplet Splitting
Multiplet splitting is a final-state effect largely affecting first row transition metals
Spin-Orbit Splitting
Spin-orbit splitting causes doublets in XPS
The Photoelectric Effect
