چکیده انگلیسی
The high-resolution infrared spectra of the monoisotopic species F35Cl16O3, F37Cl16O3, F35Cl18O3 and F37Cl18O3 have been studied in the region of the 2ν5 overtones, from 1100 to 1200 cmâ1. Both the parallel 2ν50 and the perpendicular 2ν5â2 components are clearly observed in the spectra, their origins differing by about 0.4 cmâ1. In each spectrum about 2000 transitions have been assigned, 35% of them belonging to 2ν50. The parallel and perpendicular bands in each manifold have been analyzed separately since no evidence of perturbations has been observed. The rovibration parameters of the v5 = 2, l5 = 0 and v5 = 2, l5=â2 excited states have been obtained. For the four species combining the 2ν50 and 2ν5â2 band origins with those of the ν5 fundamentals the harmonic wavenumbers, Ï50, and the x55 and g55 anharmonicity constants have also been derived.
