The spectrum of the ν7 + ν8 band of the ethylene-1-13C (13C12СH4) molecule is recorded with a Bruker IFS 125 HR Fourier spectrometer in the range from 1500 to 2100 cm–1 with a resolution of 0.0025 cm–1. As a result of analysis of the experimental spectrum, more than 1000 transitions belonging to the ν7 + ν8 band are assigned. Parameters of the Hamiltonian obtained as a result of solving the inverse spectroscopic problem reproduce 400 initial experimental energies with error close to the experimental one.
