Abstract :This paper reviews the probability of probing the unoccupied electronic states in solids by inverse photoemission spectroscopy IPES . IPES is a surface science technique to analysis the unoccupied electronic states above the Fermi level. IPES is a complementary technique to photoemission. In the IPES technique, the incoming particles are electrons and the outgoing particles are emitted photons that are consequently created by them therefore this technique is named as Bremsstrahlung Isochromate Spectroscopy. This is a common measuring mode because the photons of particular energy are identified. IPES has established one of the most powerful techniques in the study of the unoccupied electronic states in solids.Keywords : Inverse photoemission spectroscopy, Photoemission spectroscopy, Unoccupied electronic states, Fermi level, Free–electron–like transitions
