Line positions and strengths of CO_2 in the 1200–1430-cm^−1 region

The vibrational rotation spectrum of CO2 in the 1200–1430-cm−1 region has been studied at a 0.005-cm−1 resolution with a Fourier transform spectrometer. Measurements were made of line positions and strengths of the nonsymmetric CO2 species: 12C16O18O,12C16O17O, and 13C16O18O for the bands 10002–00001 and 10001–00001 and the π-π bands 11102–01101 and 11101–01101 for the 12C16O18O molecule. The line position measurements were analyzed to obtain values of band centers and upper and lower state rotational constants. The line strength data were analyzed to determined the vibrational band strengths and the coefficients of the F factors.
