Molecular Absorption Theory

Molecular Absorption Theory explains how molecules absorb specific wavelengths of light. When light passes through a substance, molecules can absorb certain energies that match the energy difference between their quantum states, causing them to transition to higher energy levels. This results in dark lines or bands in the light spectrum, known as absorption spectra. The pattern of these absorbed wavelengths helps identify and analyze the molecules present, providing insights into their structure and properties. This theory underpins techniques like spectroscopy, crucial in fields such as chemistry, astronomy, and environmental science for understanding material compositions.
