Abstract

The high‐resolution stimulated Raman spectrum of the 2ν~10~ band located at 1664.16 cm^−1^ of C~2~H~4~ has been reanalyzed, thanks to the tensorial formalism developed in Dijon for X~2~Y~4~ asymmetric‐top molecules. A total of 191 lines were assigned and fitted as a single band without including perturbations such as Fermi or Coriolis coupling constants. We obtained a global root mean square deviation of 8.5 × 10^−3^ cm^−1^. Further investigations are required to include interactions with the ν~2~ and ν~7~ + ν~10~ bands.
