What is Raman Spectroscopy?

Raman spectroscopy is a non-destructive chemical analysis technique that offers detailed information regarding chemical structure, phase and polymorphic crystallinity, and molecular interactions. It is ideal for sample identification and quantification processes. Raman spectroscopy works by shining a monochromatic light source—usually a laser—onto a sample and detecting the scattered light. Most scattered light is at the … Continue reading
