The rotational analysis of the (0,0) band of $S^{16}O_{2}$ given by Brand, Jones, and di Lauro is confirmed in general, but their values for the anisotropic electron spin fine structure constants are found to be seriously in error. Our new values remove the discrepancy in the sign of the spin-spin interaction parameter $\beta = E$ between the gas phase work and the solid state value given by Tinti. This discrepancy had been rationalized by Brand et al., in terms of a different choice of phases for the angular momentum operators, but this argument is shown to be incorrect. The spectrum of $S^{18}O_{2}$ confirms our new values completely except for the parameter ${\epsilon}_{bb}$ , where perturbation by the nearby ${\tilde{b}}^{3}A_{2}$ state is presumably responsible. en_US dc.format.extent 108161 bytes dc.format.mimetype image/jpeg dc.language.iso English en_US dc.publisher Ohio State University en_US dc.title ELECTRON SPIN FINE STRUCTURE IN THE $\tilde{a}^{3}B_{1}$ STATE OF $SO_{2}$ en_US dc.type article en_US
