The states are observed in the $50000 to 71000 cm^{-1}$ energy region by 2+1 REMPI. The similarity of the excited state vibrational frequencies to the vibrational frequencies of the ground state ion indicate the Rydberg nature of the excited states. Ab inito calculations have been performed on the ground states of the neutral and ion to determine vibrational frequencies and the ionization potential at the QCISD(T)/6-311+G(3df) level. The energies of the lowest excited states of each symmetry were obtained at the CASPT2(3,8)/ANO level. These predominantly valence states all reside below $50000 cm^{-1}$. en_US dc.format.extent 66602 bytes dc.format.mimetype image/jpeg dc.language.iso English en_US dc.publisher Ohio State University en_US dc.title INVESTIGATION OF $PF_{2}$ BY REMPI SPECTROSCOPY AND AB INITIO CALCULATIONS. en_US dc.type article en_US
