摘要

Electron-transfer (ET) reactions,between separate molecules (intermolecular) or between distinct regions within the molecule (intramolecular),are some of the most frequently encountered photochemical primary processes.In such inter- or intramolecular processes,the reaction product is usually called a charge-transfer (CT) state,or an intramolecular CT state (ICT) or exciplex (note that all these terms are widely abused in the literature,applied to any state with somewhat increased dipole moment).The pho-toinitiated ET processes and the CT states play a fundamental role in photosynthesis in plants,and in numerous existing or conceived applications,e.g.,in the molecular devices of future technologies.The interest focused on these excited states is therefore both cognitive and applied.
