Webzero-point energy, vibrational energy that molecules retain even at the absolute zero of temperature. Temperature in physics has been found to be a measure of the intensity of random molecular motion, and it might be expected that, as temperature is reduced to absolute zero, all motion ceases and molecules come to rest. In fact, however, the … WebTypes of Molecular Motion. The different types of molecular motion are described below. Translation Motion- The movement of particles or molecules from one point to another within the same axis is known as translation motion. Rotational Motion- It is the movement of particles around the axis. Vibrational Motion- one of the best examples of this ...
