WebPhotoelectron spectroscopy is a useful technique for scientists because it allows them to explore the properties of matter (gases, solids, and liquids) by measuring electron orbital energies. Scientists can infer particularly about the constituents of a substance as well as the bonds between the atoms in the material using this data. WebX-ray photoelectron spectroscopy, or XPS, is an non-destructive technique that can be used to measure the surface chemistry of a material. In XPS, an X-ray of known energy strikes an atom. A core shell electron absorbs the X-ray photon, gaining enough energy to leave its orbit. Excess energy absorbed by the electron remains as its kinetic energy.
