The frequencies of twenty-eight lines in the P-branch of the 01/sup 1/1--(11/sup 1/0, 03/sup 1/0)/sub I/ band of /sup 13/C/sup 16/O/sub 2/, observed in laser emission, and three lines in the R-branch, observed in absorption with a diode laser, have been carefully measured with stabilized CO/sub 2/ lasers. A significant improvement in the ro-vibrational constants has been obtained from a least squares fit to these data. The laser lines stabilized by saturated absorption techniques provide convenient, accurate (uncertainty <0.1 MHz) frequency references near 11.7 ..mu..m.
