Nine rotational transitions of v-italic = 0 X-italic-tilde /sup 2/B-italic/sub 1/ H/sub 2/O/sup +/ have been measured by laser magnetic resonance. Optical combination differences have been combined with the LMR data in a weighted least-squares analysis using a Watson S-italic-reduced rotational-fine structure Hamiltonian. Twenty-four molecular constants were simultaneously determined, including three hyperfine parameters and the axial components of both the anisotropic and rotational g-italic tensors. The anisotropic g-italic tensors are compared with their calculated values using the Curl relationship. An r-italic/sub 0/ structure was determined and is in good agreement with several a-italicb-italic i-italicn-italici-italict-italici-italico-italic results.
