Carbon dioxide spectral line frequencies for the 43-μm region

Abstract

The frequencies of CO₂ lines in the 3.77–4.26-μm region, which were obtained experimentally, have been compared with those listed on two tapes of the AFCRL Atmospheric Absorption Line Parameters Compilation. The experimental line frequencies were obtained in absorption using a high-resolution Michelson interferometer. Discrepancies between the present experimental values and the frequencies listed on the AFCRL tapes are tabulated. Consistency checks were also made by comparing calculated line frequencies with those on the tapes, and these findings are also reported.
