What is Molecular Spectroscopy?

Molecular spectroscopy is a process that lets scientists and researchers identify, quantify, and determine the characteristics of molecules in a compound or material by measuring how they interact with electromagnetic radiation. The process works because different types of molecules have unique responses when exposed to electromagnetic radiation.
