Abstract

The rotational, fine, and hyperfine structure in the high resolution electronic spectra of the $Ar \cdot OH/D \bar{A} \leftarrow \bar{X}$ bands has been well studied and $reported.^{1.2}$ A comparison between these results and our recent analyses on the spectra of $Ne \cdot OH/D$ reveals even more interesting information about the nature of these open-shell complexes. It is found that there are similarities and differences in the spectra of $Ne \cdot OH/D$ and $Ar\cdot OH/D$. Both Ar and Ne complexes have bands which can be characterized by transitions from the ground vibrational level in the $\bar{X}$ state to the $\bar{A}$ state levels either with or without a quantum in torsional (bending) mode. The bands of both Ar and Ne complexes, involving no quanta in the $\bar{A}$ state bending mode, show similar rotation, fine, and hyperfine structure. On the other hand, those bands involving bend excitation in the $\bar{A}$ state of $Ne \cdot OH/D$ show quite distinct differences to those of $Ar \cdot OH/D$. We have completed analyses on all observed spectra or Ar and Ne complexes. A detailed comparison on rotational, fine, and hyperfine structure as well as their physical interpretations will be discussed.
