Kesavasamy, K.; Krishnamurthy, N.

American Journal of Physics, 46, 8, 815-9, Aug 78

Discusses the vibrations of a linear triatomic chain and shows that the addition of the third atom gives rise to an extra optical branch. The nature of the normal modes in ionic crystals and molecular crystals is also discussed. (GA)
