The principal, ethane absorption in the $1940-2150cm-1$ region is due to $\nu 9+\nu 12$; the band is perturbed and our analysis will be discussed. We have determined improved ground state parameters front a combination difference analysis: \begin{eqnarray*} B_{O}&=&(663;065.8 \pm 1.8)\times 10^{-6};cm^{-1}\ D_{O}^{J}&=&(1035.0\pm1.9)\times 10^{-9};cm^{-1}\ D_{O}^{JK}&=&(4697.\pm 30.)\times 10^{-9};cm^{-1}\ H_{O}^{KKJ}&=&(17.02\pm 0.29)\times 10^{-9};cm^{-1}\ \end{eqnarray*} The stated error limits are standard errors; the more realistic 99% confidence limits are 12 times the stated standard deviations.
