Absolute intensities for over 300 lines of eleven relatively weak bands of /sup 12/C/sup 16/O/sub 2/, /sup 13/C/sup 16/O/sub 2/, /sup 16/O/sup 12/C/sup 18/O, and /sup 16/O/sup 12/C/sup 17/O near 2050 cm/sup -1/ have been measured from 0.01-cm/sup -1/ resolution laboratory spectra recorded with the Fourier transform spectrometer in the McMath solar telescope complex at the National Solar Observatory on Kitt Peak. The spectral data were obtained with a natural sample of carbon dioxide at room temperature and low pressure (<10 Torr) and have a signal-to-rms noise of roughly-equal4000. The intensities were determined using the technique of nonlinear least-squares spectral curve fitting. The measured line intensities obtained for each band have been analyzed to derive the vibrational band intensity and F-factor coefficients. The results are compared to values from the 1982 Air Force Geophysics Laboratory line parameters compilation.
