Water line parameters for weak lines in the range 7400–9600cm−1

Application of renormalized coupled-cluster methods to potential function of water

“…There are many applications involving water molecule in which the knowledge of a reliable potential energy surface is required. Selected examples of such applications include the spectrum of the water vapor, which is important for the understanding of the absorption and retention of sunlight in Earth's atmosphere and physics of other planets and stars [103][104][105][106][107][108][109][110][111][112], and combustion studies involving hot steam. For example, the…”

Water vapour line assignments in the 9250–26000cm−1 frequency range

“…Table 3 summarises the results of analysis in each of these regions. The region below 11 190 cm À1 has been the subject of studies [6,18,19,[28][29][30] which actually probe deeper than the BR results. The results for this region are therefore of less significance.…”

Fourier-transform absorption spectroscopy of H218O in the first hexade region

“…Detailed comparison of our energy levels set with compilation [6] has shown that the levels from both sets agree within 0.0012 cm À1 on average. We did not confirm 18 energy levels derived in [3][4][5]. Full set of the obtained energy levels is presented in the electronic archive attached to the paper.…”

“…The spectrum under present study is formed by transitions coming on the first hexad upper vibrational states: (101), (200), (002), (120), (021), and (040), it occupies 6000-7940 cm À1 spectral region and has been investigated, since 1986 in a number of papers [1][2][3][4][5]. Chevillard et al [1] presented first consistent study of the first hexad energy levels and line intensities.…”

“…An important set of 139 new energy levels was derived from very weak transitions of H 2 18 O present in the sample in natural abundance. Tolchenov et al [4] retrieved weak pure water vapor transitions in the 7400-9600 cm À1 region from a long path length FT spectrum. In their work, among more than 1000 lines recorded in the region overlapping with present study, 108 lines were assigned to H 2 18 O transitions reaching the (101), (200), and (002) stretching states.…”
