(mechanics) Exhibiting anharmonicity
Potential energy of a diatomic molecule as a function of atomic spacing. When the molecules are too close or too far away, they experience a restoring force back towards u0. (Imagine a marble rolling back and forth in the depression.) The blue curve is close in shape to the molecule's actual potential well, while the red parabola is a good approximation for small oscillations. The red approximation treats the molecule as a harmonic oscillator, because the restoring force, -V'(u), is linear with respect to the displacement u.
(mechanics) Exhibiting anharmonicity
A pendulum is a simple anharmonic oscillator. Depending on the mass's angular position θ, a restoring force pushes coordinate θ back towards the middle. This oscillator is anharmonic because the restoring force is not proportional to θ, but to sin(θ). Because the linear function y = θ approximates the nonlinear function y = sin(θ) when θ is small, the system can be modeled as a harmonic oscillator for small oscillations.
