Particle-hole multiplets in ${}_{}{}^{208}{}_{}{}^{}\mathrm{Bi}$ corresponding to the coupling of the $h_{\frac{9}{2}}$ proton with neutron holes in the $p_{\frac{1}{2}}$, $f_{\frac{5}{2}}$, $p_{\frac{3}{2}}$, $i_{\frac{13}{2}}$, $f_{\frac{7}{2}}$, and $h_{\frac{9}{2}}$ shells have been observed by the ${}_{}{}^{209}{}_{}{}^{}\mathrm{Bi}\mathrm{}(p,d)\mathrm{}{}_{}{}^{208}{}_{}{}^{}\mathrm{Bi}$ reaction at 35 MeV with an over-all resolution of 5 keV in the deuteron spectra. The results generally show excellent agreement with the weak coupling model except for the $h_{\frac{9}{2}}$ hole states. However the observed $h_{\frac{9}{2}}$ multiplet states do contain a large fraction of the expected strength. There is also substantial agreement with earlier ($d,t$) work except for some spin assignments and in the location of the $2^{-}$ member of the $\pi h_{\frac{9}{2}}$, ${\nu }^{-1\mathrm{}}{i}_{\frac{13}{2}}$ multiplet.
