Question

The zero point energy of a diatomic sho of vibrational frequency is

Answer 1

Explanation:

Zero-point energy, vibrational energy that molecules retain even at the absolute zero of temperature. ... But it is an axiom of quantum mechanics that no object can ever have precise values of position and velocity simultaneously (see uncertainty principle); thus molecules can never come completely to rest.

Answer 2

The vibrational zero-point energy is the energy difference between the lowest point on the potential energy surface (equilibrium energy) and the energy of the vibrationless energy level (v=0).

The Vibrational stretching frequencies of diatomic molecules depend on their inter-molecular forces. Vibrational stretching frequencies are defined as a continuous change in their bond energy at the axial points in their bond.

• A diatomic molecule has one normal mode of vibration, since it can only stretch or compress the single bond. A molecular vibration is excited when the molecule absorbs energy, ΔE, corresponding to the vibration's frequency, ν,

according to the relation,

$ΔE = hν$

where h is Planck's constant.
