    • Abstract

       

      High-resolution spectra of the 0–9, 0–10 and 0–11 bands of theA2IIuX2IIg system of (16O18O)+ ion have been studied for their rotational structure. This study enables a direct determination of the Λ-doubling parameters of theA2IIu andX2IIg states. The model of ‘pure precession’ explains, though not entirely, the Λ-doubling of theX2IIa state as arising out of its interaction with theB2Σg state. The Λ-doubling in theA2IIu state was found insignificant.
