WebJan 30, 2024 · Infrared (IR) spectroscopy is one of the most common and widely used spectroscopic techniques. Absorbing groups in the infrared region absorb within a certain wavelength region. The absorption peaks within this region are usually sharper when compared with absorption peaks from the ultraviolet and visible regions. WebThe answer to this question depends a great deal on the model that we want to use to describe the interaction of light with matter. At the macroscopic level, we may say that light is reflected or absorbed. ...
