Inverse photoelectron spectroscopy IPES

The ionization potential of a molecule is the energy from the ground state of the molecule (HOMO) to the vacuum level. It is measured using UPS or XPS. The electron affinity of the molecule is the energy from the vacuum level to the LUMO. It is measured using inverse photoelectron spectroscopy (IPES) [15]. The values obtained in the gas phase are different from those obtained in the solid state, and shifts due to amorphous versus crystalline regions can be noticed. [Pg.632]

The sample is exposed to an electron beam of known energy. The electrons undergo transitions to empty states in the conduction band, emitting a photon (also known as inverse photoelectron spectroscopy, IPES)... [Pg.440]

The elemental composition within the surface may be determined, but quantification is difficult In addition, information regarding the empty density of states can be revealed. It therefore suppHes complementary information to inverse photoelectron spectroscopy (IPES) and scanning tunnelling spectroscopy (STS). [Pg.509]
