THE purpose of this communication is to present a calculation of the electron affinities of some molecules from charge transfer spectra. Mulliken's1 theory for a charge-transfer process leads to the expression: where hνmax. is the energy corresponding to the most probable electronic transition, ID and EA are the vertical ionization potential of the electron donor and the vertical electron affinity of the electron acceptor. Δ represents the stabilization energy, relative to the ground-state, of the excited state in the nuclear configuration corresponding to the ground-state. This relation has been confirmed for some series of various donors with one acceptor2,3 and for series of a particular donor with various acceptors4.
