Line Positions and Absolute Intensities in the Laser Bands of Carbon-12 Oxygen-17 Isotopic Species of Carbon Dioxide

Global Fittings of the Vibrational–Rotational Line Positions of the 16O12C17O and 16O12C18O Isotopic Species of Carbon Dioxide

“…The calibration factor for Ref. (11) has been found to be statistically insignificant and has been set to 1. The determined calibration factors and the RMS deviations for each spectrum are given in Table 1.…”

Infrared Spectra of the 16O12C17O and 16O12C18O Species of Carbon Dioxide: The Region 500–1500 cm−1

“…They are given in terms of atomic masses in Table 1. The knowledge of the real isotopic abundance of 16 Table 1, when the contributions of the other mass 46 species are discarded. The real accuracy, taking into account possible impurities in the sample, is estimated better than 0.1%.…”

“…In a separate paper (7), results of the global fittings of effective Hamiltonian parameters to infrared line positions for both 16 18 O species have been reported. The eigenfunctions of these effective Hamiltonians have been presently used for fitting effective dipole moments parameters to line intensities of the bands lying in the ν 2 and ν 1 spectral regions.…”

“…In the course of this work, it turned out that new line intensity measurements for the 16 O 12 C 18 O species were necessary.…”

“…The results of the line intensity fittings in each spectral region are given in Section III. Comparisons of the calculated line parameters with the corresponding 16 (8) and GEISA (9) databases are displayed in Section IV.…”
