Abstract

Far-infrared pure rotational spectra of H₂¹⁶O, H₂¹⁸O, HD¹⁶O, HD¹⁸O, D₂¹⁶O, and D₂¹⁸O have been measured with a high-resolution Fourier-transform spectrometer with an apparatus function of 0.004 cm⁻¹ in the region from 20 to 350 cm⁻¹. Altogether about 1200 lines have been assigned and measured with an accuracy that is believed to be ~0.0002 cm⁻¹ (~6 MHz), so that many of the frequencies should be of use in the calibration of far-infrared spectrometers.
