The debye frequency of a crystal is the theoretical maximum frequency of vibration for the atoms that make up the crystal It was proposed by Peter Debye as part of the Debye model. It plays a role in the computation of the specific heat capacity of solids and in theoretical estimates of rates of diffusion. It is related to the speed of sound (v_{s}) in the crystal and the volume V per atom as follows :## References

$nu\_m\; =\; left(frac\{3N\}\{left(4\; pi\; V\; right)\}right)^\{1/3\}nu\_s$

Where $N/V$ is the number density of atoms in the crystal.
