Line intensities of the: ν3, 4ν2, ν1+ν3, 3ν1 and 2ν1+2ν2 bands of 16O12C32S molecule

Abstract The line intensities of the ν3 band of OCS used for atmospheric retrievals, has been measured. The spectra have been recorded with the Reims Fourier transform spectrometer. Other bands of OCS 4ν 2 , ν 1 +ν 3 , 3ν 1 and 2ν1+2ν2 were recorded to obtain the line intensities. The results are compared to usual databanks (HITRAN or GEISA). From the measured line intensities, it has been possible to estimate the square of the vibrational dipole moment matrix element ( in debye 2 ) , equal to 0.1313 1 , 7.840 9 ×10 −4 , 1.158 1 ×10 −3 , 1.218 3 ×10 −5 , 1.192 3 ×10 −5 , respectively, for ν 3 , 4ν 2 , ν 1 +ν 3 , 3ν 1 and 2ν1+2ν2.

Line intensities of : the 10 micrometers region revisited

Abstract New line intensity measurements in the 10 μm region of 14 N 2 16 O have been performed using FTS in Paris and Reims. About 150 lines in hot bands, including those of the forbidden 0330–0110 band, have been measured for the first time. The new observations together with those available in this region have been used in the fit of effective dipole moment parameters. A dimensionless weighted standard deviation of 1.28 and a RMS deviation of 4.2% have been obtained. Some disagreements with previous measurements and with the HITRAN and GEISA databases have been pointed out for the 0001–1000 and 0220–0000 bands.
