The eight first vibrational states of the water molecule: measurements and analysis

Analysis of the first triad of interacting states (020), (100), and (001) of D216O from hot emission spectra

“…This study confirms a conclusion of previous works that two types of calculations discussed above provide complementary tools for water spectra assignment and analyses: global variational calculations (as described by Partridge and Schwenke [20,21], Polyansky and coworkers [38]) offer a physically consistent view on an entire set of all rovibrational states and effective polyad calculations using effective Hamiltonians with adequate convergence and extrapolation properties [7][8][9]39] could give better accuracy locally together with a supplementary insight to resonance mixing of rovibrational wave functions. …”

Fourier transform measurements of water vapor line parameters in the 4200–6600cm−1 region

“…[18,19,21,49,50] were used to assign lines to the H 2 16 O species. Practically, for all the levels obtained from assigned transitions, the energy levels are in very 2 18 O lines, the energy levels from several experimental studies were used, namely [26] (for the (0 0 0) and (0 1 0) states), [15,28] (for the first triad of vibrational interacting states (0 2 0), (1 0 0), and (0 0 1)), [25,51] (for the second triad of vibrational interacting states (0 3 0), (1 1 0), and (0 1 1)), and [17,21,27] (for the (0 4 0), (1 2 0), and (0 2 1) states).…”

Frequency measurement of pure rotational transitions in the v2= 1 state of H2O

“…For recent years, comprehensive measurements and analysis of vibrationally excited states including (0,1,0) state have been achieved by Coudert et al and Lanquetin et al [5,[24][25][26][27]. In the newest article by Coudert et al [25], more than 1500 FIR transitions in the 50-500 cm À1 region were measured in a emission spectrum from discharged sample.…”

“…In the newest article by Coudert et al [25], more than 1500 FIR transitions in the 50-500 cm À1 region were measured in a emission spectrum from discharged sample. Frequencies of pure rotational transitions in the (0,1,0) state found in the table 7 of [25], together with the O À C differences in it, were referenced in the present work as the most up to date frequency data.…”
