“…The literature data concerning these minor isotopologues is limited. In 1977, Winther measured 121 and 48 pure rotational transitions of H2 18 O and H2 17 O, respectively, by absorption FTS in natural water vapour below 501 cm -1 [33]. Later, 255 absorption transitions were reported for H2 18 O in Refs.…”

The rotational spectrum of water vapour highly enriched in 18 O has been studied by high resolution (≈ 0.001 cm -1 ) Fourier transform spectroscopy at the AILES beam line of the SOLEIL synchrotron. The room temperature absorption spectrum has been recorded between 40 and 700 cm -1 . The 18 O enrichment of the sample was about 97% while the gas pressure and the absorption pathlength were set to 0.97 mbar and 151.75 m, respectively. The spectrum contains more than 4800 rotational transitions from seven water isotopologues (H2 18 O, H2 16 O, H2 17 O, HD 18 O, HD 16 O, HD 17 O, D2 18 O). The assignments were performed using known experimental energy levels as well as calculated line lists based on the results of Schwenke and Partridge. The amount and accuracy of the reported line positions represent an important extension compared to previous works. Overall, lines of about 2570 transitions are observed for the first time and 35, 41, 50, and 16 new energy levels are determined for H2 18 O, H2 17 O, HD 18 O, and HD 17 O, respectively. The set of derived energy levels shows a number of important differences from those recommended by an IUPAC-task group. Compared to the HITRAN2016 database, numerous deviations of line positions (up to 0.15 cm -1 ) are found for the H2 17 O, H2 18 O, HD 17 O, and HD 18 O species. Incomplete and wrong HITRAN's assignments of more than 90 transitions for H2 18 O, H2 17 O and HD 18 O are identified. Overall, the measured line positions will allow to significantly refine and complete the sets of empirical energy levels of H2 18 O, H2 17 O, HD 18 O and HD 17 O in the ground vibrational state.

“…Overall, 498 rotational absorption and emission transitions in the (000) and (010) states were reported in Refs. [14,15,17,21,[33][34][35][36][37] for H2 18 O. As for H2 17 O, all the 364 transitions known in the far-IR range are pure rotational transitions [14,15,17,21,[33][34][35][36].…”

“…Second the dipole moment of formaldehyde has relatively large value too [8,9]. In that sense formaldehyde molecule can be compared with water molecule, which has also large rotational constants, dipole moment, and very wide rotational spectrum [10][11][12][13].…”

“…In the last few decades, numerous spectroscopic studies on the H 2 18 O molecule have been carried out with microwave [1][2][3][4][5], Fourier-transform infrared [6][7][8][9][10][11][12][13][14][15][16][17][18][19][20][21][22][23][24], and cavity ring-down spectroscopy [25,26] in the near-IR and visible region. More than 800 energy levels have been reported from our previous Fourier-transform study [27,28].…”
