Infrared Spectra of Some Common Functional Groups

WebNov 9, 2024 · Infrared (IR) spectroscopy is a very useful method for detecting the characteristic bonds of many functional groups through their absorption of infrared light. If you shine infrared light on a molecule, it is possible that the molecule absorbs energy from light. Absorbed energy can cause a bond to stretch or bend. WebIR absorption is common for molecular species with a low energy gap among rotational and vibratory states. The net shift of dipole moment in a substance when it vibrates or revolves is a prerequisite for IR absorption. Infrared spectroscopy applications.
