IR (infrared spectroscopy)

Infrared (IR) spectroscopy is a scientific technique used to identify and analyze chemicals by shining infrared light on a sample. Different molecules absorb specific wavelengths of IR light based on their bonds and structure, causing them to vibrate in characteristic ways. By measuring which wavelengths are absorbed, scientists can determine the presence of particular functional groups or compounds within the sample. IR spectroscopy is widely used in chemistry and medicine for qualitative and quantitative analysis of substances, providing valuable information about molecular composition without damaging the sample.
