Robert N. Compton
Professor Emeritus
Dr. Compton earned a B.A. in physics from Berea College in 1960, an M.S. in physics from the University of Florida in 1963, and a Ph.D. in physics from the University of Tennessee in 1965. He worked at Oak Ridge National Laboratory for several years before joining the faculty of the University of Tennessee full-time.

Research
Our research involves fundamental studies in the area of Chemical Physics. The formation, structure and decay of singly- and multiply-charged negative ions are studied both experimentally and theoretically. The binding of electrons to molecules with sufficiently large dipole or quadrupole moments results in weakly-bound dipole or quadrupole bound anions. The electron affinities of these molecules are inferred from Rydberg Charge exchange cross sections or directly determined from measurements of electric field detachment thresholds. Multiply-charged negative ions are produced using electro-spray ionization or through negative ion charge exchange with an alkali atom (e.g., TCNQ- + Na → TCNQ– + Na+). This research benefits from collaborations with the Aarhus (Denmark) Electrostatic Ion Storage Ring. Studies of molecules possessing extremely large electron affinities (e.g., PF6, PtF6, AuF6) is also underway. Vibrational spectroscopy of singly- and multiply-charged negative ions is also carried out at the FELIX Free Electron Laser in Holland. Another component of our research involves investigations of Chirality at the fundamental and applied level. This includes the development of a new chiro-optical method: multi-photon ionization circular dichroism.
