AP Chem Name_____ Block_____ Photoelectron Spectroscopy (PES) Watch the video “ Photoelectron Spectroscopy – Part 1.” X-ray photoelectron spectroscopy (XPS) is a surface-sensitive quantitative spectroscopic technique based on the photoelectric effect that can identify the elements that exist within a material (elemental composition) or are covering its surface, as well as their chemical state, and the overall electronic structure and density of the electronic states in the material. This video shows how Ionization Energies helped prove the shell-model of the atom and then how Photoelectron Spectroscopy proved the quantum mechanical model X-ray Photoelectron Spectroscopy (XPS) For each and every element, there will be a characteristic binding energy associated with each core atomic orbital i.e. each element will give rise to a characteristic set of peaks in the photoelectron spectrum at kinetic energies determined by the photon energy and the respective binding energies. Leilani Salgado AP Chemistry 9/27/20 Photoelectron Spectroscopy Questions 1. What determines the position and the height (intensity) of each peak in a photoelectron spectrum? The number of ejected electrons vs the corresponding ionization energy for the ejected electrons. Therefore, the peaks determine the electrons in different subshells.
