Crystal lattice vector

WebReciprocal vectors are formed by choosing a vector perpendicular to two lattice vectors and of length reciprocal to the third lattice vector. Linear combinations formed from these reciprocal vectors and the Miller indices are vectors that are in the same direction as the poles to the corresponding planes.
