Absorption chemistry background

Electronic structure and absorption in effective chromophores 5.5.9.1 Absorption chemistry background... 

Mixed-valence chemistry was reviewed in the late 1960 s both by Robin and Day (4) and by Hush (5). Their work provided the beginnings of a theoretical background for understanding the properties of mixed-valence compounds including the low energy absorption bands which have been termed Intervalence Transfer (IT) or Metal-Metal Charge Transfer (MMCT) bands. 

Some references are made in the following survey of spectra to this analogy between diffraction and absorption edge spectra. However, the real purposes of the survey are to provide background for application of these spectra to catalyst problems and to point out the empirical relationships between these spectra and structural chemistry.
