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.

Band origins as listed in Table 10.1
Band origin calculations from the constants in Table 91 disagree with those listed in Table 101: the line wavenumbers follow the latter.
Using the constants in Table 91 gives the branch with wavenumbers decreasing as J increases, but the lines on the tape vary in the opposite manner.
No R branch for this band. Too weak?
The substates are marked *, not C or D.
No constants in Table 91 for one of the states.
The C and D states show quite different discrepancies.

Mean difference = 0.0398 ± 0.0331 cm−1
Note: The error sum of squares for least squares fits to the differences between the experimental and AFCRL wavenumbers (difference 2 − 1, in table) are:

The adjusted wavenumbers (penultimate column in the table) were obtained by adding the differences from the least squares fit of degree 1 (shown in the last column of the table) to the AFCRL compilation wavenumbers.

Table I
Discrepancies Between Calculated Wavenumbers and Those on the AFCRL Tape II
Band origins as listed in Table 10.1
Band origin calculations from the constants in Table 91 disagree with those listed in Table 101: the line wavenumbers follow the latter.
Using the constants in Table 91 gives the branch with wavenumbers decreasing as J increases, but the lines on the tape vary in the opposite manner.
No R branch for this band. Too weak?
The substates are marked *, not C or D.
No constants in Table 91 for one of the states.
The C and D states show quite different discrepancies.
