This technique let researchers view how the molecules spun and vibrated after the chemical reaction.

The molecules vibrate in tune, at terrific frequency, and the light can pass perfectly.

Beyond our three-dimensional world, the molecules vibrate at a much faster or higher rate of speed.

As air (or any other medium) is heated, its molecules vibrate more rapidly, and move over a greater distance.

This heat energy can then cause the molecules to vibrate faster.

The more the molecules vibrate, the higher the temperature.

Any vibration which makes the surrounding molecules of air vibrate can cause sound.

A molecule can vibrate in many ways, and each way is called a vibrational mode.

Temperature makes a difference because at higher temperatures, molecules vibrate more vigorously.

Nor is a gas, in which the molecules vibrate at random.
