What is anharmonicity? Draw a diagram for the variation of potential energy with intermolecular distance for an anharmonic and harmonic oscillator.
In classical mechanics, anharmonicity is the deviation of a system from being a harmonic oscillator. An oscillator that is not oscillating in simple harmonic motion is known as an anharmonic oscillator where the system can be approximated to a harmonic oscillator and the anharmonicity can be calculated using perturbation theory. If the anharmonicity is
