The theoretical interpretation of Cs II has been extended and now includes the 5p/sup 5/ns (n = 6--12), 5p/sup 5/np (n = 6--8), 5p/sup 5/nd (n = 5--11), 5p/sup 5/nf (n = 4--8), 5p/sup 5/ng (n = 5--10), and 5p/sup 5/nh (n = 6--8) configurations. Most levels are well represented in the single-configuration approximation when far configuration interactions are included through effective electrostatic parameters. Explicit interactions of low-lying 5p/sup 5/nd+5p/sup 5/(n+1)s configurations have been determined. For most configurations, good jK coupling is found. Purities of the levels in jK coupling and the LS composition of the eigenvectors are given. The intermediate-coupling eigenvectors have been used to calculate magnetic-dipole hyperfine-splitting factors, and these are compared with 167 experimentally determined values from our earlier work.
