Excitation spectra

An excitation spectrum shows how a material or atom absorbs energy at different wavelengths or frequencies, revealing possible energy states. When energy, like light or electricity, is applied, electrons in the material can jump to higher energy levels. The spectrum maps these absorption points, indicating the specific energies needed for electrons to become excited. This information helps scientists understand the material’s electronic structure and properties, such as color, electrical behavior, or reactivity. Essentially, excitation spectra are like a fingerprint, showing how a substance responds to different energies and providing insights into its underlying atomic or molecular makeup.
