Summary:Title screen
Two weak “hot” absorption bands, ν7 þν10 ν10 and ν10 þν12 ν10, of ethylene, C2H4, were analyzed for the first time with high resolution using the Fourier transform interferometer Bruker IFS-120 HR. As the result of analysis we assigned about 930 and 370 transitions (404 and 185 upper state ro-vibrational energy values) with J max: ¼ 27, Kmax: a ¼ 14 and J max: ¼ 20, Kmax: a ¼ 9 for the bands ν7 þν10 ν10 and ν10 þν12ν10, respectively. Strong local resonance interactions of the vibrational state ðv10 ¼ v12 ¼ 1Þ with the five other states, and of the state ðv7 ¼ v10 ¼ 1Þ with the seven other states were taken into account, and a set of 77 varied parameters, which reproduce the initial experimental data with the rms deviation of 6.1 104 cm1 which is close to experimental uncertainties, was obtained.
