What is Dissociation energy?

The term dissociation energy may be appreciated by reference to potential energy internuclear distance curves. At about 0 K all molecules have no rotational energy but are merely vibrating with their zero-point energy. Thus, diatomic molecules are in the v = 0 vibrational level. The energy required to separate the stable molecule A - B initially in the v = 0 level into two unexcited atoms A and B, that is: A - B → A+B is known as the dissociation energy (D).

How to Calculate Anharmonicity constant when dissociation energy is given?

FAQ

What is Anharmonicity constant when dissociation energy is given?
The Anharmonicity constant when dissociation energy is given formula is defined as the deviation of a system from being a harmonic oscillator in relation to the vibrational energy levels of a diatomic molecule and is represented as xe=(ω'^2)/(4*De*ω') or Anharmonicity constant=(Vibrational wavenumber^2)/(4*Dissociation energy of potential*Vibrational wavenumber). Vibrational wavenumber is simply the harmonic vibrational frequency or energy expressed in units of cm inverse and Dissociation energy of potential is the energy which is measured from the bottom of the potential.
