Study of the High Resolution Spectrum of the ν6+ν10 Band of the 13C2H4 Molecule

Аннотация

High resolution spectrum of the ¹³С₂H₄ molecule recorded in the region of 1980–2080 cm^–1 with a resolution of 0.0025 cm^–1 using a Bruker IFS 120HR Fourier spectrometer is analyzed. As a result of solving the inverse spectroscopic problem, spectroscopic parameters of the vibrational state ( ν₆ = ν₁₀ = 1, B_3u) of the examined molecule are obtained for the first time that allows rotational energy levels to be reproduced with an accuracy close to the experimental one (a total of 677 rovibrational energies corresponding to 2300 transitions up to J^max = 40 and \( {K}_a^{\mathrm{max}}=15 \)).
