Title: ANTICROSSING RESONANCES IN THE FIR LMR SPECTRUM OF $FO_{2}$: A CLASSIC EXAMPLE

Abstract: We have detected strong laser magnetic resonance (LMR) spectra of the $FO_{2}$ radical on two closely spaced laser lines around $919 \mu m$. The spectra show two distinct types of pattern, one has an extended progression of narrow resonances while the other exhibits an extremely strong, broad, doublet with an unsymmetrical lineshape. We have assigned these spectra following predictions of nearby zero field transitions using our earlier mm-wave $results^{1}$. The patterns arise from a very complicated set of anticrossings involving seven different rotational levels and give information on the off diagonal elements of the spin-rotation and spin g-factor tensors. Although the observed spectra are complicated, it is likely that similar mechanisms will dominate the FIR LMR spectra of all heavier asymmetric top radicals
