The $\nu 6(A2\prime \prime )$ parallel band of $C3D6$ near $2336cm-1$ has been recorded with resolution between 0.018 - $0.024cm-1$ on the University of Tennessee five meter Littrow spectrometer. The K-structure for each J value is unresolved below J = 20. Above this some structure is visible but cannot be assigned to specific K values. The Q branch is partially resolved into its J structure and two hot band Q branches are observed. Preliminary analysis of the ground state combination difference yielded $B0=0.461410\pm 0.000012cm-1$ and $D0J=(3.895\pm 0.071)\times 10-7cm-1$. Refined parameters for the ground and upper states will be reported.
