Crystal ratio
For typical ionic solids, the cations are smaller than the anions, and each cation is surrounded by coordinated anions which form a polyhedron. The sum of the ionic radii determines the cation-anion distance, while the cation-anion radius ratio (or ) determines the coordination number (C.N.) of the cation, as well as the shape of the coordinated polyhedron of anions.

Webare called the motional parameters of the crystal, and C0 is the shunt capacitance. C0 is real—it can actually be measured with a simple capacitance meter. The motional arm parameters, on the other hand, are equivalents and not simple to measure. How much the frequency of the crystal is pulled or deviated will depend on the ratio of C0/C1.
