However, the separation of the rotational from the vibrational motion is more difficult and is not completely possible.

This leaves 3N - 6 vibrational motions (or modes of vibration).

No doubt heat is transferred to the piece of iron, which causes vibrational motion in its molecules.

In addition, young spiders demonstrate vibrational motion when approached by a predator.

In other systems, vibrational and rotational motions also contribute degrees of freedom.

And because vibrations involve shifting electrons around, the vibrational motion has an electric field associated with it.

The vibrational motion of electric charges can produce such a thing.

The vibrational motion of the molecule can be figured out by examining how much energy was lost during the scattering.

A standard example is the phonon, which characterizes the vibrational motion of every atom in the crystal.

Every now and again, one is absorbed and excites vibrational motion.
