👉 The term "chromophor" is a technical term used in the field of spectroscopy and color chemistry. It refers to a type of molecule that has two or more colors, often in different wavelengths, due to its structure. Chromophores are typically characterized by their ability to absorb light at specific wavelengths and emit other wavelengths when they are excited. They can be found in various materials such as glass, plastics, metals, and even gases like air.
