WebJan 30, 2024 · If the wavelength of the incident beam has enough energy to promote an electron to a higher level, then we can detect this in the absorbance spectrum. Once in the excited state, the electron has higher potential energy and will relax back to a lower state by emitting photon energy. WebPhotoelectron spectroscopy (PES) is an experimental technique that measures the relative energies of electrons in atoms and molecules. Scientists often use PES to study the elemental composition of materials …
