 Title: ANALYSIS OF THE $\nu_{6}$ BAND OF $CHD_{2}F$ Creators: Eggers, D. F.; Johns, J. W. C. Issue Date: 1983 Abstract: A sample of $CHD_{2}F$ has been synthesized, in isotopic purity above $95\%$. The four fundamentals $\nu_{4}, \nu_{5}, \nu_{6} and \nu_{9}$ all occur in the general region of $CO_{2}$ laser lines. Optical pumping of this substance results in FIR laser action on a number of lines; some of the strongest ones are associated with absorption of the $CO_{2}$ pumping lines by the $\nu _{6}$ band. Assignments of the FIR emission lines will be discussed, along with progress on the analysis of the band. We show that one of the weak FIR lines from pumping $CD_{3}F^{2}$ is actually due to a small amount of $CHD_{2}F$ present as an isotopic impurity. Further, some OODP signals from a sample of $CD_{3}F^{3}$ are also shown to be due to $CHD_{2}F$. 1. M. S. Tobin, private communication and to be published. 2.
