 Title: THE $C^{3}\Pi$ STATE OF THE SO RADICAL Creators: Clerbaux, C.; Colin, R. Issue Date: 1991 Abstract: The $B^{3}\Sigma^{-} -X^{3}\Sigma^{-}$ emission spectrum of the SO radical has been reinvestigated at high resolution from a microwave discharge in $SO_{2}$ using a Bruker FTS 120HR spectrograph. Since $1932^{1}$, the $B^{3}\Sigma^{-}$ state has been known to undergo predissociation and to present complex rotational perturbations on the v=1,2 and 3 vibrational levels, but no satisfactory $analysis^{2}$ of these features, caused by a $C^{3}\Pi$ state, has been performed. A new attempt which investigated both $S^{16}O$ and $S^{18}O$ isotopomers has led to new information concerning the $C^{3}\Pi$ state and will be presented. FA4(4:08) and FA5(4:25) will be presented here at the request of the author who must return to Japan on $Friday.^{1}$E. Martin, Phys. Rev. 41, 167 (1932) $^{2}$D. Abadie, Ann.
