Spectroscopic methods

Definition

Spectroscopic methods are analytical techniques used to measure the interaction of light with matter, allowing scientists to determine the composition, structure, and properties of materials. These methods rely on various forms of electromagnetic radiation, including UV-Vis, IR, and NMR spectroscopy, to provide insights into molecular vibrations, electronic transitions, and chemical environments. They are crucial for characterizing smart polymers, as these materials often respond to external stimuli, and understanding their behavior requires detailed analysis at the molecular level.
