Polarized $^{8}\mathrm{Li}$ nuclei recoiling from the reaction $^{7}\mathrm{Li}(d, p)^{8}\mathrm{Li}$ were implanted in Au, Pd, and Pt foils, and the Knight-shifted values of the $^{8}\mathrm{Li}$ magnetic dipole moment in these metals were measured by a resonant depolarization technique. From measurements of the spinlattice relaxation times of $^{8}\mathrm{Li}$ implanted in Au, Pd, and Pt, the Knight shifts of $^{8}\mathrm{Li}$ in these metals were estimated. A corrected value for the magnetic dipole moment of $^{8}\mathrm{Li}$ was found to be $\ensuremath{\mu}(^{8}\mathrm{Li})=(1.65335\ifmmode\pm\else\textpm\fi{}0.00035){\ensuremath{\mu}}_{N}$. Attempts were also made to measure the quadrupole couplings of $^{8}\mathrm{Li}$ in single crystals of Be and Mg. While the resonance lines could not be distinctly resolved, upper and lower limits have been deduced for $|\frac{{e}^{2}\mathrm{qQ}}{h}|$ in these two metals.
