title: High Dispersion Spectroscopic Observation of Venus. IV: The Weak Carbon Dioxide Band at 7883 A.
abstract: The average rotational temperature of the Cytherean atmosphere above the cloud tops was found to be T(rot) = 244 +/- 10 K based on twelve plates of the 7883-A CO(2) band. If the temperatures found from the 7820-A band on the same plate are averaged with the temperatures found from the 7883-A band, we obtaina temperature of T(rot) = 245 +/- 6 K. The observations of Venus were made between April and December of 1967. Laboratory measurements of the 7883-A band are lacking, but we infer that the band is half as strong as the 7820-A band.
