Abstract
The spectroscopy of fluorine atoms in a neon matrix is used to develop a model of excited state electronic guest-host coupling of F atom rydberg scares and $Ne^{+}F^{-}$ charge transfer states. F atoms are produced in a matrix of original composition $F_{2}/Ne$ (1/1000) by photodissociation of $F_{2}$ at 14 cV. Synchrotron radiation in the range of 60 nm lo 160 nm is used to probe the molecular $F_{2}$ and atomic F concentration by fluorescence. Absorption, excitation, and emission spectra are used to characterize the excited state potentials. Excitations and emissions of both the F atom Rydberg elates and the $Ne^{+}F^{-}$ charge transfer states are observed. These spectra are used to develop a configuration coordinate model of the manifold of excited states which describes the nonradiative relaxation and the observed emissions.
