dc.description.abstract We $reported^{1,2}$ the high resolution electronic spectra of the $Ne \cdot OH/D \bar{A}-\bar{X}$ transitions, terminating in the $\bar{A} (0,1^{0},1), (0.1^{0}, 1)$ and $(0.1^{0}.1)$ levels, with detailed analyses including rotational. fine, and hyperfine structure. The notation $(v_{OH}, n^{x}, v_{1})$ indicate respectively the quantum numbers of the OH moiety stretch, the OH internal rotation with the projection K superscripted, and the van der Waals stretch. The previous analyses reveal that the parity splitting for the $\bar{X}$ state of $Ar\cdot OH/D$ is indeterminate with our resolution, but the parity splitting in the $\bar{X}$ state of $Ne \cdot OH/D$ is well determined with a magnitude approximately 10 times larger than the reported $value^{3}$ in $Ar \cdot OH/D$. In addition, we also observed a large spin-rotation parameter $\gamma$ in the $\bar{A} (0,1^{0}, 1)$ level of $Ne \cdot OH$ (as well as $Ne \cdot OD)$. The value of $\gamma$ is 180(6) MHz for $Ne \cdot OH$, and is approximately 3 times larger than the corresponding parameters in the other $\bar{A}$ state vibrational levels of $Ne \cdot OH [\gamma=65(19) MHz]$ and $Ar\cdot OH [\gamma=46(12) MHz]$. We have additionally obtained the spectrum of $Ne \cdot OH$ terminating in the $\bar{A}$ $(0,1^{1},1)$ level, which also possesses a large $\gamma$ value of 160(24) MHz. A model based upon perturbation theory for open-shell complexes at the free rotor limit is proposed and successfully explains the spin-rotation interaction. Moreover, a parity splitting in the $\bar{A} (0.1^{1},1)$ level of $Ne \cdot OH$ has also determined. The details of analyses will be presented. en_US
