The spectrum of Bi II was remeasured in the wavelength range 620-74 nm, using different hollow cathode light sources, resulting in 91 new classified lines. We found two even and eight odd new levels. Fine and hyperfine structure analysis has been performed with a many configurations approach. We determined for all levels the Landé g J -factors and the hfs A-constants, using the wavefunctions calculated. For the first time, radial hyperfine structure parameters were determined for the excited configurations 6s 2 6pnl (l = s, p, d, f, g). We will also discuss the important role of configuration interaction effects on fine and hyperfine structures.
