Lorentzian model

The Lorentzian model describes how certain physical systems, like atomic or molecular resonances, respond to external stimuli such as light or electromagnetic waves. It characterizes the shape of a peak in the response—called a resonance—using a specific mathematical function. This model captures how the response is strongest at a particular frequency and gradually decreases on either side, forming a bell-shaped curve with characteristic width. It's widely used in spectroscopy and optics to understand and analyze resonant behaviors, providing insights into the properties of materials and systems at their natural frequencies.
