摘要:
High resolution (0.0025 cm(-1)) spectrum of the (C2H4)-C-13 molecule recorded in the 2330-2500 cm(-1) spectral region with a Bruker 120HR Fourier spectrometer is theoretically analyzed. The spectroscopic parameters of the (v(2) = v(10) = 1, B-2u) vibrational state of the molecule are determined for the first time by fitting the experimental data that allow the rotational energy values (529 rovibrational energies corresponding to 2400 transitions with J(max) = 30 and K-a (max) = 13) to be reproduced with accuracy close to experimental uncertainties.
