These differences are explained in terms of the energeticsof the electron extraction process. This research was supported by the U.S. Atomic Energy Commission, the National Science Foundation and the Army Research Office (Durham). One of us (N. E. G.) is grateful to the New York University Arts and Science Foundation for a travel grant and the Research Corporation for an equipment grant. The assistance of Larry Rubin and his staff at the National Magnet Laboratory at M.I.T., which is supported by the National Science Foundation, is gratefully acknowledged. The assistance of C. Penn, J. Tinkel, F. Van Nostrand and J. Becker in some of the experi- ments is also appreciated.

N2 - The photoinjection efficiency of holes into anthracene by irradiated aqueous I3- electrodes is decreased by the application of an external magnetic field of up to 100 kG. The effect is attributed to the magnetic field enhanced dissociation of electronically excited I2 (I2*) in solution. The I2* is proposed as a photodissociation product of excited I3-. Atomic iodine does not seem to play a major role in the photoinjection process. The action spectrum is given and a kinetic scheme is proposed. Preliminary results on tetracene, perylene, and dinitronaphthalene show great differences from anthracene.
