Fig. 31. Schematic potential energy diagram for interaction between absorbate A and a surface M. G is the ground state of the molecular complex, M" + A is an ionic state, (M + A) is an antibonding state, M + A is a state where the adsorbate is excited and the substrate is in its ground state, M + A is a state where the substrate is excited and the adsorbate is in its ground state. Possible electronic transitions from the ground state G to the various excited states are indicated by the shaded Franck-Condon region. Electron bombardment can presumably excite any of these states. (From Ref. )...
