dc.description.abstractFourier transform spectra at $0.05 cm^{-1}$ resolution were obtained in the 750-900 $cm^{-1}$ region of the sum and difference bands of $\nu_{2}$ with $\nu_{7}$ of $C_{3}O_{2}$. Sharp Q branches occur for each $\nu_{7}$ state in the sum bands, but only a number R-branch band heads and no recognizable Q branches in the difference bands. Assignments of the sum band Q branches through $\nu _{7} = 6$ were made, and molecular constants were determined for the $\nu_{2} + \nu_{7}^{1\leftarrow 0}$ transition at $819.7 cm^{-1}$. Using the model of Weber and Ford, $^{1}$ the $\nu_{7}$ potential function in the $\nu_{2} = 1$ state was found to have a $1.2 cm^{-1}$ barrier with a minimum at $a = 4.9^\circ$, where $2\alpha$ is the angular deviation from linearity. The Q-branch positions predicted from the calculated energy levels fit those observed within several $cm^{-1}$. In the difference bands, the calculated positions of the R branch band heads agree with the sharp peaks observed.en_US
