Hyperfine splittings in the 2${\mathit{p}}_6$, 2${\mathit{p}}_7$, and 2${\mathit{p}}_{10}$ states of the 4${\mathit{p}}^5$5p configuration of ${}_{}{}^{83}{}_{}{}^{}\mathrm{Kr}$ (I=9/2) have been measured using saturated absorption laser spectroscopy. Computer simulations involving composite line shapes have been employed to reduce resolution difficulties. While the determination of hyperfine-coupling constants A and B in the 2${\mathit{p}}_7$ and 2${\mathit{p}}_{10}$ states is straightforward, this process is complicated by overdetermination in the 2${\mathit{p}}_6$ state. Our measurements of A (2${\mathit{p}}_6$) and (${2\mathrm{p}}_6$,2${\mathit{p}}_7$,2${\mathit{p}}_{10}$) represent the first determinations of these constants. With these measurements, hyperfine couplings for all eight states exhibiting hyperfine structure in the 4${\mathit{p}}^5$5p manifold now exist. The results provide a good test of semiempirical calculations of hyperfine structures.
