In contrast to a previous study, we find that the sign and magnitude of the anisotropic g-factor $g_{\ell}$ for $\nu^{\prime} = 0$ is consistent with that expected from Curl's relationship. However, at higher energies $g_{\ell}$ changes sign, and possible explanations for this trend will be examined. The magnetic and electric quadrupole hyperfine constants were determined for $OD(A^{2}\Sigma^{+},\nu^{\prime} = 0-3$), and the constants for $\nu^{\prime} = 2,3$ are reported here for the first time to our knowledge. The derived values are consistent with available ab initio calculations. en_US dc.format.extent 172276 bytes dc.format.mimetype image/jpeg dc.language.iso English en_US dc.publisher Ohio State University en_US dc.title ON THE ENERGY DEPENDENCE OF THE ZEEMAN AND HYPERFINE PARAMETERS IN THE $A^{2}\Sigma^{+}$ STATE OF OH AND OD en_US dc.type article en_US
