Relation between lattice parameter and interplanar spacing

The magnitude of the distance between two adjacent and parallel planes of
atoms (i.e., the interplanar spacing ) is a function of the Miller indices (h, k,
and l) as well as the lattice parameter(a). For non-cubic systems, the relation is much complex than shown above.
