Analyzing and Predicting Spectroscopic Data

The interaction of electromagnetic radiation with the structure of molecules in the sample and their study is referred spectroscopy. Several spectroscopic methods are used to acquire sample information, and these methods are proved to be accurate, fast, and non-destructive. The information obtained about the content and composition of molecules from these spectroscopic methods is called spectroscopic data.
