Abstract: A sample of $CH_{2}DF$ was prepared in high isotopic purity and the IR spectrum was run on a Bomcm instrument at $0.005 cm^{-1}$ resolution. The $v_{6}$ band has strong A-type transitions that could be assigned for J values up to 31; for many lower J some K's up to 10 were also found. There are numerous B-type transitions as well, though with lower intensity. The analysis was based on the A-type transitions and gave a reasonable fit with inclusion of some sextic distortion constants. There is a $(K. K+2)$ Coriolis resonance of $K_{a} = 10$. in this band with $K_{a} = 8$ in the V5 band whose center is some $117 cm^{-1}$ higher: the rotational levels cross at about $J = 14$. The molecular constants will be compared with those for the symmetrical isotopic molecules, with adjustment for isotopic relationships. This sample was also optically pumped with a $CO_{2}$ laser, and five SMMW laser lines were found. The IR measurements permit assignment of two; however, the other three present more of a problem.
