The parallel component of the $2\nu 3$ band of $\mathrm{<mrow\; data-mjx-texclass="ORD">12</mrow>}CD3F$ has been recorded with a resolution of $20-25\times 10-3$ $cm-1$. The $(\alpha B-\alpha A)$ term is small and therefore the J-manifolds are unresolved for J$ < 15$ and only partially resolved for greater J values. The band has been analyzed using standard techniques and preliminary values of $\nu 0=1977.178(3)$ $cm-1$ and $\alpha B=(B\prime \prime -B\prime )=3.086(7)\times 10-3$ $cm-1$ have been obtained. A value of $2.85(5)\times 10-3$ $cm-1$ has been obtained for $\alpha A$ form a band contour fit to the P(10) multiple. Details of the analysis and further results will be reported.
