Question

what the energy of vibrating molecules?​

Answer 1

A molecular vibration is a periodic motion of the atoms of a molecule relative to each other, such that the center of mass of the molecule remains unchanged.A fundamental vibration is evoked when one such quantum of energy is absorbed by the molecule in its ground state.

Answer 2

When a molecule absorbs energy proportionate to the vibration's frequency molecular vibration is activated.

Explanation:

• A molecular vibration is a periodic motion of a molecule's atoms relative to one another in which the molecule's center of mass remains unchanged.

• According to the relationship, molecular vibration is activated when the molecule absorbs energy proportional to the vibration's frequency, v. When a molecule in its ground state absorbs one of this quantum of energy, a fundamental vibration is elicited. The first and perhaps higher overtones are aroused when many quanta are absorbed.
