Photoelectron spectroscopy翻译

WebPhotoelectron spectroscopy is an extension of the photoelectric effect (see radiation: The photoelectric effect), first explained by Einstein in 1905, to atoms and molecules in all energy states. The technique involves the bombardment of a sample with radiation from a high-energy monochromatic source and the subsequent determination of the kinetic energies … WebAboutTranscript. In the analytical technique of photoelectron spectroscopy (PES), a sample is ionized using high-energy radiation, and the kinetic energies of the ejected electrons (called photoelectrons) are measured. From this, we can determine the binding or ionization energy of each electron in the atom or molecule.
