We show that application of the methods of the quantum theory of angular momentum enables one to obtain frequency equations for vibrational modes of uniform isotropic elastic sphere, cylindrical rod, and infinite plate and results in a natural classification of these modes. We discuss how these models can be applied to describe vibrations of metal nanoparticles and semiconductor nanocrystals.
