Abstract

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.
