Abstract
Zeeman-shifted pure rotational transitions of $HO_{2}$ have been recorded at fields from 0 to 20 kGauss, using seven CW laser lines (of $H_{2}O$, $D_{2}O$ and $CH_{3}OH$) as fixed-frequency absorption sources. Since the initial assignment of unknown Zeeman-shifted spectra cannot be obtained with the help of combination difference, some new mathematical approaches will be described which have proved useful for the case of a near-prolate asymmetric top in a doublet electronic state. At the present time, ten asymmetric-rotor transitions have been assigned. These data are sufficient to give preliminary values for the rotational constants A, B, C from a rigid-rotor fit, and a preliminary value for one spin-rotational interaction constant, but insufficient to give good information on centrifugal distortion terms.
