| Featured Article | | What is Raman Spectroscopy? | | Raman spectroscopy is a spectroscopic technique that utilizes scattered light to probe the vibrational energy modes present within a sample. It is named after C. V. Raman who pioneered its observation in 1928 alongside his collaborator K. S. Krishnan. Originally, the Raman effect was observed using sunlight and mercury arc lamps.
