摘要: Abstract The absorption spectrum of oxygen-17-enriched water vapor in the 12,055–12,260 cm−1 region was recorded with a continuous-wave cavity ring-down spectrometer (CW-CRDS) at room temperature. In total, 1342 lines were observed this region, while more than 1400 transitions assigned based on previously published experimental energies and variational calculations results Partridge Schwenke. typical frequency accuracy 0.002 cm−1 achieved work. Three hundred fifty-eight ro-vibrational energy levels H217O isotopologue retrieved, which belong to ν 1 + 2 3 =3.5 4 polyads: (0 3), 2), (1 1), (2 0), (3 0 0) states. One ten them reported for first time. Comparisons line positions those HITRAN database given H216O isotopologues. obtained vibration-rotation also compared MARVEL values.
