Nuclear magnetic resonance measurements were performed on the ground states of ${}_{}{}^{169}{}_{}{}^{}\mathrm{Lu}$, ${}_{}{}^{171}{}_{}{}^{}\mathrm{Lu}$, ${}_{}{}^{172}{}_{}{}^{}\mathrm{Lu}$, ${}_{}{}^{173}{}_{}{}^{}\mathrm{Lu}$, and ${}_{}{}^{177}{}_{}{}^{}\mathrm{Lu}$ and on the $\frac{23}{2^{-}}$ isomeric state ${}_{}{}^{177m}{}_{}{}^{}\mathrm{Lu}$. The radioactive isotopes were implanted into hcp Co single crystals using the mass separator ISOLDE at CERN. For ${}_{}{}^{169}{}_{}{}^{}\mathrm{Lu}$, ${}_{}{}^{171}{}_{}{}^{}\mathrm{Lu}$, ${}_{}{}^{172}{}_{}{}^{}\mathrm{Lu}$, ${}_{}{}^{173}{}_{}{}^{}\mathrm{Lu}$, and ${}_{}{}^{177}{}_{}{}^{}\mathrm{Lu}$ the quadrupole subresonance structure could be resolved well. With the magnetic hyperfine fields and the electric field gradient of $\mathrm{Lu}Co\left(\mathrm{hcp}\right)$ derived from the results on ${}_{}{}^{177}{}_{}{}^{}\mathrm{Lu}$, the magnetic moments and electric quadrupole moments of ${}_{}{}^{169}{}_{}{}^{}\mathrm{Lu}$, ${}_{}{}^{171}{}_{}{}^{}\mathrm{Lu}$, ${}_{}{}^{172}{}_{}{}^{}\mathrm{Lu}$, and ${}_{}{}^{173}{}_{}{}^{}\mathrm{Lu}$ were determined. The nuclear moments of the high-spin isomer ${}_{}{}^{177m}{}_{}{}^{}\mathrm{Lu}$ were determined with a resonance-offset technique.
