WebWhen infrared radiation is directed at matter, it can stimulate the movement of molecules and atomic bonds. This movement can take various forms, such as rotation or vibration. Depending on how the molecule is excited, we can obtain information about the structure and identity of the irradiated material. Can infrared light analyze all materials? WebDec 15, 2024 · The spikes are called absorption bands in an IR spectrum. A molecule have a variety of covalent bonds, and each bond have different vibration modes, so the IR spectrum of a compound usually show multiple absorption bands. The horizontal axis …
