THE ELECTRONIC EMISSION SPECTRUM OF CuCl

Author Institution: Department of Chemistry, University of Waterloo; Laboratoire de Photo Physique Moleculaire, Bat. 210, Universit\'{e} de Paris XIThe electronic emission spectrum of CuCl has been observed. The spectrum was observed when CuCl powder and Cu metal were placed in a copper hollow cathode lamp operated with He gas. On the basis of recent ab initio calculations, the labels for the electronic states were revised and the 0-0, 0-1 and 1-0 bands of the $a^{3}\Sigma^{+}_{1} - X^{1}\Sigma^{+}(A^{1}\Pi-X^{1}\Sigma^{+}),b^{3}\Pi-X^{1}\Sigma^{+}(B^{1}\Pi-X^{1} \Sigma^{+}), b^{3}\Pi_{o}-X^{1}\Sigma^{+} (C^{1}\Sigma^{+}-X^{1}\Sigma^{+}), A^{1}\Pi-X^{1}\Sigma^{+} (D^{1}\Pi-X^{1}\Sigma^{+})$ and $B^{1}\Sigma^{+}-X^{1}\Sigma^{+}(E^{1}\Sigma^{-}-X^{1}\Sigma^{+})$ transitions were measured. The old labels are in parentheses. Improved band constants were obtained for the excited and ground states
