THE technique of X-ray photoelectron spectroscopy (ESCA) is already proving to be a valuable new tool for investigating a variety of problems in chemistry and physics. It entails direct measurement of the binding energies of electrons in the inner shells of the atoms in a molecule and the results have revealed the existence of a chemical shift1–3.
