Spectroscopy
What is Raman Spectroscopy?
Raman spectroscopy is a powerful, non-destructive analytical technique that reveals the molecular “fingerprints” of materials using light. By measuring how molecules scatter laser light, this method provides rich information about a substance’s chemical composition, structure, and vibrational behavior. It is widely valued for its ability to analyze samples in their natural state—without requiring preparation—making it one of the most versatile tools in modern science.
What makes Raman spectroscopy truly fascinating is its vast range of applications. From identifying unknown materials and detecting impurities to studying biological tissues, pharmaceuticals, gemstones, and advanced nanomaterials, Raman opens a window into the microscopic world with remarkable precision. Its speed, accuracy, and real-time analysis capabilities have made it indispensable in research labs, industries, and forensic investigations—unlocking insights that drive innovation across science and technology.
