 Title: MEASUREMENT OF THE ROTATIONAL SPECTRUM OF $OH^{+}$ AND $OD^{+}$ BY LASER MAGNETIC RESONANCE Creators: Gruebele, M.; Müller, R. P.; Saykally, R. J. Issue Date: 1985 Publisher: Ohio State University Abstract: Rotational fine structure transitions have been observed for the $OH^{+}$ and $OD^{+}$ molecular ions V=O in the $X^{3}\Sigma^{-}$ ground state by far-infrared laser magnetic resonance spectroscopy. The ions were generated in an intracavity discharge using 1 torr of helium and 30 mT of $H_{2}O/D_{2}O$. Measurements of N=1+O, N=2+1 and N=3+2 have been made up to 17 kG for both species, with resolution of the $OH^{+}$ hyperfine structures. The data is being analyzed using a modified Tinkham-Strandberg Hamiltonian for $^{3}\Sigma$ states. Results of this analysis will be used to accurately predict astrophysically accessible rotational transitions.
