Chemical Effects in XPS Chemical shift: change in binding energy of a core electron of an element due to a change in the chemical bonding of that element. Qualitative view: Core binding energies are determined by: • electrostatic interaction between it and the nucleus, and reduced by: • the electrostatic shielding of the nuclear charge from all
