High-spin states in doubly odd ${}^{170}\mathrm{Re}$ have been populated via the ${}^{142}\mathrm{Nd}({}^{32}\mathrm{S},p3n\gamma )$ reaction at beam energies of 155 and 166 MeV. $\mathrm{K}X\text{−}\gamma$ and $\gamma \text{−}\gamma$ coincidences have been measured using a detector array consisting of 12 high-purity germanium detectors with BGO suppressors. A rotational band is identified and assigned to ${}^{170}\mathrm{Re}$ for the first time. This band is proposed to be built on the $\pi h_{11∕2}\otimes \nu i_{13∕2}$ two-quasiparticle configuration by comparing the band properties with known bands in neighboring nuclei and the cranked-shell model calculations.
