In chemistry, charge-transfer (CT) complex, or electron donor-acceptor complex, describes a type of supramolecular assembly of two or more molecules or ions. The assembly consists of two molecules that self-attract through electrostatic forces, i.e., one has at least partial negative charge and the partner has partial positive charge, referred ...
Charge-transfer bands of transition metal complexes result from shift of charge density between molecular orbitals (MO) that are predominantly metal in character and those that are predominantly ligand in character. If the transfer occurs from the MO with ligand-like character to the metal-like one, the transition is called a ligand-to-metal ...

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.
Structure of the charge-transfer complex between pyrene with the electron-deficient 1,3,5-trinitrobenzene. [3] Alternatively, electron-deficiency describes molecules or ions that function as electron acceptors. Such electron-deficient species obey the octet rule, but they have (usually mild) oxidizing properties.
Consider all the fees involved in international money movement — currency conversion charges, international transfer fees and foreign transaction costs. A single world currency would eliminate ...
The abscissa is the transferred amount of charge Δe or the induced polarization P, the ordinate the Gibbs free energy. ΔG(0) ‡ = λ o /4 is the reorganization energy at Δe = 0.5, it corresponds to the activation energy of the self-exchange reaction. Of course, in this classical model the transfer of any arbitrary amount of charge Δe is ...
