## Abstract

Two-dimensional nutation pure NQR experiments on $^{35}Cl$ have been carried out on a single crystal of $NaClO_3$. The 22D nutation experiment separates out different orientations of each chemically equivalent site in a unit cell as a separate frequency in the $\omega _1$ domain. The squares of the observed frequencies lie on a straight line with respect to the squares of the offsets, confirming the expected offset dependence quantitatively. The intercepts at zero offset yield the relative orientations of the efg tensors with respect to the axis of the radiofrequency coil.
