Abstract
The high-resolution IR spectrum of the fundamental band ν6 of 13CHF3 molecule, located in the region of 450–750 cm–1, has been investigated. The spectrum was analyzed based on the ground-state combination-difference method. About 5500 transitions were assigned as a result of the analysis, based on which 2607 experimental values of ro-vibrational energies in the state ν6 = 1 were determined. The results surpass the data known in the literature, both in the amount of obtained experimental data and in the number of highly excited ro-vibrational energy levels extracted from these data. Based on the information extracted from the spectrum, the spectroscopic parameters of the state under consideration were determined, which reproduce the initial data with an error of 4.4 × 10–5 cm–1.
