Abstract

Fourier-transform microwave spectroscopy was applied to observe the J = 1-0 rotational transition of the ortho-H₂-H₂O complex and isotopologues in the ground Σ₀ state (H₂ in the j_H2 = 1 state and H₂O in the ground 0₀₀ state) to obtain precise molecular constants. Observed spectra were split into three hyperfine components, confirming the complexes are the ortho-H ₂/para-D₂ species. The determined nuclear spin-spin coupling constant indicates H₂ is rotating almost freely in the complex; the Σ₀ state is nearly of j_H2 = 1 and k_H2 = 0. For the ortho-H₂ species, the nuclear spin-rotation coupling constant was also determined.
