ν 1 −ν 2 , ν 3 −ν 2 , ν 1 , and ν 3 bands of H 2 16 O: line positions and strengths

High-resolution spectra of H216O were recorded with a Fourier-transform spectrometer covering transitions in the (100)–(010), (001)–(010), (100)–(000), and (001)–(000) bands. The measured line frequencies were used to determine high-accuracy values of rotational energy levels in the (100) and (001) vibrational states. Measurements of the line strengths were fitted to a model in which 19 transition moment parameters were determined for the B-type bands and 8 parameters for the A-type bands. The fitting technique did not consider interactions between the (020), (100), and (001) vibrational states. The experimental results provide a more accurate representation of the line positions and strengths than those available at present for these bands.
