  We propose a method to perform a configuration determination for chiral
and/or polar crystals by utilizing anisotropy of NMR shift. The chirality
(handedness) or polarity of a crystal, that is characterized by its sign, can
be extracted from the asymmetric magnetic-field angle dependence of NMR shift
in the appropriate plane, as the configuration is reflected in the off-diagonal
components of the shift tensor. This method is applicable to the triclinic,
monoclinic, and trigonal crystal structures among 230 crystallographic space
groups, and the appropriate planes to extract the asymmetric field-angle
dependence are tabulated for all relevant space groups. We discuss how to
determine the appropriate plane, and to identify each contribution of twin
domains, and so on, by using the specific examples of Te, IrSn$_{4}$ and
RhSn$_{4}$, and the spontaneous symmetry-breaking phases of URhSn. We also
argue that an absolute-configuration determination is also possible in
accordance with the relation between chirality or polarity of crystal and the
sign of the relevant off-diagonal component of the shift tensor, provided by
theoretical evaluation of internal magnetic field from surrounding ions, and/or
by experimental input on the shape of the asymmetric etch pit on the cleaved
face of crystal.
