چکیده انگلیسی
The absorption spectrum of water vapor enriched in oxygen-17 has been recorded by a continuous-wave cavity ring-down spectrometer (CW-CRDS) at room temperature in the 12,277-12,894 cmâ1 region. The typical sensitivity of 2â¯Ãâ¯10â10 cmâ1 allowed the detection of water vapor transitions with intensities larger than 1â¯Ãâ¯10â28 cmâ1/(molecule cmâ2). In total, more than 3400 lines were observed in the recorded spectra with a typical frequency accuracy of 0.002 cmâ1. In which more than 3400 transitions were ro-vibrationally assigned to five water isotopic species (H217O, H216O, H218O, HD16O, and HD17O) using the known empirical energy levels combined with the calculated variational line lists based on the results of Partridge and Schwenke. About 1300 transitions of H217O were assigned, leading to the determination of new energy levels of 17 vibration states. Those assigned H217O transitions are involved with the upper vibration states of (013), (023), (032), (051), (061), (070), (080), (090), (112), (131), (150), (160), (211), (230), (301), (310), and (320). The maximum values of the rotational numbers J and Ka were 16 and 9, respectively. The 5ν1 band of HD17O was assigned for the first time as well. The line positions and energy levels determined in this work were compared with literature, and it shows a significant improvement of the line positions of H217O and HD17O in the 12,277-12,894 cmâ1 region.
