Abstract

Individual components of the Zeeman transitions in the rotational spectrum of H₂O and D₂O were resolved in fields of 25-30 kG. This allowed determination of the g values with greater accuracy than previous measurements. The g values obtained for H₂O were g(5₂₃) =0.6959±0.001 and g(6₁₆) =0.6565± 0.001. The g values obtained for D₂O were g_aa=0.3233±0.001, g _cc= 0.3580±0.001, and g_cc=0.3226±0.001. Analysis of the combined results indicates that the g values for H₂O are positive and that the values are g_aa=0.6650±0.002, g _bb= 0.7145±0.002, and g_cc=0.o465±0.002. Hyperfine structure on the 6₁₆-5₂₃ transition in H ₂O was observed in a maser spectrometer, and the spin-rotation and spin-spin coupling constants were obtained. The measured value of the rotational transition frequency was 22 235 079.85±0.05 kHz. The magnetic susceptibility anisotropies and molecular quadrupole moments were determined in H₂O.
