    Charge-Transfer (CT) Transitions
    In molecules where electron donor groups are separated from electron acceptor groups by a conjugated bridge, an intramolecular charge transfer can occur upon excitation. These transitions typically result in very intense colors (high molar absorptivity, $\varepsilon$). The mechanism is frequently central to the function of industrial dyes, such as those based on [quin…

    Linked via "charge transfer"

    In solid-state physics, particularly in magnetic materials, the concept of the exchange interaction is extended. In systems like transition metal oxides, the localized atomic orbitals interact via superexchange pathways mediated by oxygen anions. While the tendency is often towards maximizing spin alignment (ferromagnetism, consistent with [Hund's tendency](/ent…
