Scientific paper

Ethylene is a naturally occurring compound in ambient air that affects atmospheric chemistry and global climate. The C_2H_4 spectrum is available in databases only for the 1000 and 3000 Cm-1 ranges. In this work, the ethylene absorption spectrum was measured in the 6030-6250 Cm-1 range with the use of a high resolution Bruker IFS 125HR Fourier-spectrometer and a two-channel opto-acoustic spectrometer with a diode laser. As a secondary standard of wavelengths, the methane absorption spectrum was used in both cases. A preliminary analysis was realized thanks to the tensorial formalism developed by the Dijon group that is implemented in the XTDS software package. We considered the two combination bands ν_5+ν_9 and ν_5+ν11 as an interacting dyad. Parameters for the ν_9/ν11 dyad were fitted simultaneously from a re-analysis of previously recorded supersonic expansion jet FTIR data, while parameters for the v_5=1 Raman level were taken from literature. More than 600 lines could be assigned in the 6030-6250 Cm-1 region (and also 682 in the 2950--3150 cm-1 region) and effective Hamiltonian parameters were fitted, including Coriolis interaction parameters. The dyad features are globally quite well reproduced, even if there are still problems at high J values.
