The high-resolution stimulated Raman spectrum of the 2ν10 band located at 1664.16 cm-1 of C2H4 has been reanalyzed, thanks to the tensorial formalism developed in Dijon for X2Y4 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 ν2 and ν7 + ν10 bands.
