What is the principle of photoelectron spectroscopy? The principle upon which photoelectron spectroscopy (PES) is based is simple. If a molecule is excited by a high-energy photon in the ultraviolet region of the spectrum that has sufficient energy to ionize the molecule, the excited species will eject electrons.
How is photoelectric effect Applied spectroscopy? Photoelectron spectroscopy involves the measurement of kinetic energy of photoelectrons to determine the binding energy, intensity and angular distributions of these electrons and use the information obtained to examine the electronic structure of molecules.
How many types of Photoelectron spectroscopy are there? The field is usually arbitrarily divided into two classes: ultraviolet photoelectron spectroscopy (UPS) and X-ray photoelectron spectroscopy (XPS). The names derive from the energies of the photons used in the particular spectroscopy.
