Enhancement of the sensitivity of magnetic resonance force microscopy allowed the extension of the technique to observe half-integer quadrupolar nuclei. This is demonstrated for various different compounds and nuclei with different spin numbers. The possibility of obtaining spatially localized spectral information through the quadrupole interaction is implemented by using nutation NMR. This enables us to superimpose a contrast function on the image of materials depending on their local lattice structure. This opens up new possibilities for both surface and subsurface studies in materials chemistry.
