spectrochemistry

Spectrochemistry is a branch of chemistry that studies the relationship between the properties of matter and the electromagnetic radiation it absorbs or emits. This interaction occurs when electrons within atoms or molecules transition between different energy levels. When matter is exposed to electromagnetic radiation, it can absorb specific wavelengths, causing electrons to jump to higher energy states. Conversely, when excited electrons return to lower energy states, they emit radiation at characteristic wavelengths. By analyzing the wavelengths of absorbed or emitted light, scientists can deduce information about the composition and structure of a substance. Different types of spectrochemistry exist, categorized by the region of the electromagnetic spectrum used, such as ultraviolet-visible spectroscopy, infrared spectroscopy, and atomic emission spectroscopy. These techniques are invaluable in various fields, including chemical analysis, quality control, and scientific research, enabling the identification and quantification of elements and compounds.
