Abstract
Several band systems of YbF and YbCl have been observed from the beam-gas chemiluminescent reactions of Yb with $F_{2}$ and $ClO_{2}$. The general features of the A-X and B-X systems in the blue-green correspond very well with those studied previously by Gatterer, et al.,$^{1}$ and by Barrow and $Chojnicki.^{2}$ Spectra with more clearly resolved features are obtained from these reactions at higher pressures, with argon as a carrier gas. This has permitted a more extensive vibrational analysis of the A-X system of YbF and the A-X and B-X systems of YbCl, and molecular constants for these band systems will be reported at the meeting.
