"WebApr 3, 2024 · Forced Oscillations and Resonance. When a system (like a simple pendulum is displaced from its equilibrium position and released, it oscillates with its natural frequency ω and the oscillations are called free oscillations. They die out eventually due to damping forces. However, they can be maintained by an external agency. " - Oscillation in chemistry

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. The typical vibrational frequencies range from less than 10 Hz to approximately 10 Hz, corresponding to wavenumbers of approximately 300 to 3000 cm and wavelengths of approximately 30 to 3 µm. For a diatomic molecule A−B, the vibrational frequency in s is given by , where k is the force con… WebJan 15, 2024 · 12.11: Oscillating Reactions.
