We have resorted to fittings to Hamiltonian secular equations of dimension as large as $15 \times 15$, supplemented by second-order perturbation shifts computed from the empirical electronic state interactions. A sensitive test of the accuracy of the parameters of each state and the derived potential curves is whether the off-diagonal spin-orbit perturbation elements are proportional to the computed vibrational overlap integrals. The results which we present are obtained from several stages of iteration and exhibit consistency in most cases. en_US dc.format.extent 128647 bytes dc.format.mimetype image/jpeg dc.language.iso English en_US dc.publisher Ohio State University en_US dc.title VALENCE EXCITED STATES OF CS: A STUDY OF EXTENSIVE SPIN-ORBIT PERTURBATIONS en_US dc.type article en_US
