There are three types of energy levels in a molecule, rotational, vibrational and electronic energy level. Among them, knowledge about vibrational energy level is a must.
Vibrational energy is calculated by considering the molecule as a harmonic oscillator.  This way we can get a formula for the vibrational energy. This formula is very important because it gives such information that is a break through in science.

We know that, all the things in the universe are in motion but at absolute zero of temperature, they become complete rest. But, do all the things become rest at absolute zero?
Well, at absolute zero, the rotational energy of the molecule is zero but it possesses some vibrational energy even at absolute zero of temperature.

In this video, I have explained everything about vibrational energy level and how there is some vibrational energy left in the molecule even at absolute zero.
