Title:TWO-PHOTON IONIZATION STUDY OF THE LOW LYING STATES OF UN+
Author(s):VanGundy, Robert A.
Contributor(s):Heaven, Michael; Persinger, Thomas D.
Subject(s):Ions
Abstract:The electronic structures of UN and UN$^{+}$ are of interest for the testing and development of relativistic quantum chemistry methods. The ground state UN was probed by Matthew and Morse$^{1}$, who found that the electronic configuration (5f$^{2}$7s) differed from that of the isoelectronic UO$^{+}$ cation (5f$^{3}$). In the present study we examine the ionization energy of UN and the low energy states of UN$^{+}$ by means of pulsed-field ionization zero kinetic energy photoelectron spectroscopy (PFI-ZEKE). Resonantly enhanced two photon ionization (R2PI) coupled with a time of flight mass spectrometer was used to confirm production of the UN molecule and locate suitable electronically excited states for subsequent access to UN$^{+}$ via high-n Rydberg states. The results will be compared to the predictions from ligand field theory and high-level ab ignition calculations. 1. D. J. Matthew and M. D. Morse, J. Chem. Phys. 138, 184303 (2013)
