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. The results are presented as a PES spectrum, which shows the photoelectron count on the y-axis and binding energy on the x-axis.
