The $\nu 1(A1)$ and $2\nu 5(A1)$ bands have been recorded on the University of Tennessee five meter Littrow spectrometer with resolutions from 0.010 - $0.030cm-1$. Approximately 200 lines in $\nu 1$ have been assigned. The band is perturbed above J = 12 but appears normal below this except for the K = 5 subband. Preliminary analysis of $\nu 1$ for the lines with yields $\nu 0=2090.820\pm 0.004$ $cm-1,\alpha 1A=(A\prime \prime -A\prime )=(2.040\pm 0.006)\times 10-2$ $cm-1$ and $\alpha 1B=(B\prime \prime B\prime )=-(1.815\pm 0.020)\times 10-3$ $cm-1$. The $2\nu 5$ band near $2115cm-1$ has also been assigned. Further analysis of these two bands including a GSCD analysis will be reported.
