In chemistry, intervalence charge transfer, often abbreviated IVCT or even IT, is a type of charge-transfer band that is associated with mixed valence compounds. It is most common for systems with two metal sites differing only in oxidation state. Quite often such electron transfer reverses the oxidation states of the sites. The term is frequently extended to the case of metal-to-metal charge tra… Webintervalence-band transitions are presented in Sec. 111 while the procedure used in determining the momentum matrix el- ements from the k.p method is also described in …
