History Of Raman Spectroscopy. In the 1960s laser Raman spectrophotometers using a 6943 nm ruby laser and a 6328 nm He-Ne laser appeared although the output power was only a few tens of milliwatts. The principles of Raman spectroscopy have been understood for the past 80 years and are based on the Raman effect the phenomenon of inelastic scattering of light Raman scattering which was discovered by Dr. History History of Raman spectroscopy Discovered by Dr. It developed as the molecular analog of Castaings electron microscope.

Raman spectroscopy is a technique commonly used to identify molecules in the field of Chemistry by their vibrational rotational and other low-frequency modes. The phenomenon involves the interaction of photons with a molecule followed by inelastic scattering typically at a lower energy. History of Raman Scattering In 1928 Raman and Krishnan observed the phenomenon that is now known as the Raman Effect and is the basis for Raman Spectroscopy. The visible laser lines are usually used as the excitation sources for.

Raman spectroscopy is a molecular spectroscopic technique that utilizes the interaction of light with matter to gain insight into a materials make up or characteristics like FTIR. In this history review the development of tipenhanced Raman spectroscopy TERS is analyzed from the perspective of scientific instrumentation development. TERS is a powerful and labelfree tool for nanocharacterization still mainly an academic tool built from the achievements in Raman spectroscopy surfaceenhanced Raman spectroscopy scanning probe microscopy. History History of Raman spectroscopy Discovered by Dr. The phenomenon involves the interaction of photons with a molecule followed by inelastic scattering typically at a lower energy. Since the development of the first commercial Raman spectrometer in 1953 advances in lasers and detectors and the discovery of new phenomena have expanded the use of this technique in several research fields.
