dc.description.abstractReports of a preliminary sort concerning the investigation of the infrared spectrum of $C_{2}D_{2}$ under high dispersion from 500 to 8000 K have been given by Talley and Nielsen both at previous Ohio State Symposia and in the $literature^{1}$. Thirty-nine bands were observed with a prism-grating spectrometer. More recently, $Saksena^{2}$ has published results on twelve photographic bands of $C_{2}D_{2}$ from 8500 to 13,000 K. The present total of observed bands of $C_{2}D_{2}$ is, thus, fifty-one, of which twenty-two have been resolved and analyzed. The subject of the present discussion is an attempt to correlate all of these data, and to obtain the wave numbers of the harmonic frequencies and the anharmonic constants which can then satisfactorily be used to predict the observed band centers of the remaining bands not used in the calculation. This attempt appears to have been successful in that the agreement between observed and predicted band centers is in general to about 0.1 percent. In addition, the infrared bands resolved by the writers were analyzed for rotational constants, and for the vibrationrotation interaction constants. Virtually perfect agreement exists between the rotational constants thus calculated and those reported by Saksena.en_US
