Abstract
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, I
D and E
A 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.
