Spectroscopy is a scientific technique used to analyze the interaction between matter and electromagnetic radiation. By studying the light emitted, absorbed, or scattered by materials, scientists can gain insights into the composition and structure of substances. This method is widely used in fields such as chemistry, astronomy, and biochemistry. Different types of spectroscopy, like infrared spectroscopy and NMR spectroscopy, allow researchers to identify molecular structures and understand chemical properties. The data obtained can reveal vital information about the physical and chemical characteristics of materials, making spectroscopy an essential tool in both research and industry.
