Description
The rutile crystal structure contains vacant channels along the tetragonal $c$-axis that provide both sites and a diffusion path for small interstitial impurities. Here, we present beta-detected nuclear magnetic resonance ($\beta$-NMR) measurements of the quadrupole splitting of implanted $^8$Li$^+$ in two isostructural rutile single crystals: TiO$_2$ and MgF$_2$. We compare our results with supercell density functional theory (DFT) calculations to establish the crystallographic site of the implanted ion.
