Abstract

High-resolution spectra of H₂¹⁶O were recorded with a Fourier-transform spectrometer covering transitions in the (010)–(000) band from 1066 to 2582 cm⁻¹. The measured line frequencies were used along with additional data taken from studies at microwave and far-infrared frequencies in an analysis to obtain rotational energies of levels in the (000) and (010) states. Measurements of the line strengths were fitted by least squares to a model in which the dipole moment matrix elements were represented by as many as 19 expansion coefficients. The results produced computed line strength values that are in excellent agreement, on the average, with the 874 experimental transitions included in the analysis. These results provide a more accurate representation of the line positions and strengths for the (010)–(000) band than are currently available on the HITRAN absorption line parameter compilation.
