Coulomb excitation studies have been performed on an enriched ${}_{}{}^{189}{}_{}{}^{}\mathrm{Os}$ target with a 56 MeV ${}_{}{}^{16}{}_{}{}^{}\mathrm{O}$ beam. Gamma rays were measured in coincidence with the backscattered ${}_{}{}^{16}{}_{}{}^{}\mathrm{O}$ ions. Rotational bands built on ${\frac{3}{2}}^{-}\mathrm{}\left[512\right]\mathrm{}$, ${\mathrm{½}}^{-}$ [510] up to spin $\frac{11}{2}$ have been identified.
