Spectroscopy

Spectroscopy is one of the most used tools to explore properties of matter and is an umbrella term for different techniques such as infrared spectroscopy, visible light spectroscopy, UV-light spectroscopy, X-ray spectroscopy, Raman spectroscopy and nuclear magnetic resonance. Spectroscopy instruments can be stand-alone devices, but are increasingly integrated as part of other equipment, for example in combination wit (more)h confocal microscopy.
