| Abstract: | The R-branch head of the 0001 ← 0000 band of 12C16O2 has been recorded with Doppler-limited resolution using a tunable laser difference-frequency spectrometer. J values to 140 were measured at temperatures to 985 K. The data have been combined with extremely precise transition frequencies for 0 ≤ J ≤ 76 measured with a Fourier transform interferometer to obtain an improved set of spectral constants for this ν3 band of CO2. |
