WebPhotoelectron spectroscopy (PES) is a technique that is used to gather information about the electrons in an atom. In PES, an atom is bombarded with photons. Some of the photons are absorbed and electrons are emitted. The electrons are collected and their energy is analyzed. During PES, we know the energy of the photons we excite the chrome password インポート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.
