spectroscopy
Radiation absorption study
Spectroscopy is the study of how matter interacts with light and other electromagnetic radiation.
Different substances absorb and emit radiation at characteristic wavelengths, creating patterns that reveal their composition and structure.
Scientists use spectroscopy to identify chemicals, analyze distant stars, and probe molecular behavior: Mass spectroscopy detected traces of the compound.
