Absolute intensity measurements of CO_2 bands in the 2395–2680-cm^−1 region

Absolute intensities for over 800 transitions belonging to twelve bands of 12C16O2, 16O12C18O, 16O12C17O, and 16O13C18O molecules in the 2395–2680-cm−1 spectral region have been derived using a nonlinear least-squares spectral fitting procedure. The data used in the analysis were recorded at room temperature and low pressure (<10 Torr) with the 0.01-cm−1 resolution Fourier transform spectrometer in the McMath solar telescope complex at the National Solar Observatory. The measured intensities obtained for each band have been analyzed to derive the vibrational band intensity and F-factor coefficients. The results are compared with other published values.
