چکیده انگلیسی
High-resolution Fourier-transform spectra of water samples enriched by deuterium and oxygen-18 at room temperature are analyzed in the range 969-2148 cmâ1. Line positions of about 2470 transitions up to Jmax = 22 and Ka max = 12 of the ν2 bands of the HD18O and D218O molecules are reported. This has allowed the determination of extended sets of rotational energies of the (0 0 0) and (0 1 0) vibrational states for both molecules. The generation function model of an effective rotational Hamiltonian was used in the data reduction to account for the strong centrifugal distortion of the rotational levels. Values of effective Hamiltonian parameters have been determined. The RMS standard deviations of the least-squares fits of the energy levels were 2.4 Ã 10â4 cmâ1 for 293 energy levels of the ground state and 3.2 Ã 10â4 cmâ1 for 281 energy levels of the (010) state of D218O, and 2.6 Ã 10â4 cmâ1 for 227 energy levels of the ground state and 4.2 Ã 10â4 cmâ1 for 246 energy levels of the (0 1 0) state of HD18O. Comparisons of obtained data with the theoretical predictions as well as with other observations are presented.
