Applied spectroscopy

Applied spectroscopy is a way for scientists to study molecules. It is like looking at the molecules under a special kind of microscope. But instead of seeing the molecules with our eyes, we can see them with a tool called spectroscopy. Spectroscopy is kind of like a rainbow made of light. Different molecules have different kinds of light waves that they give off, and scientists can use these light waves to identify what kind of molecules are present in a sample. Scientists have used this tool to study the atmosphere, figure out what kinds of materials are in food and understand more about how plants and animals work.
