Description

Principle Raman Spectroscopy is a scattering technique which analyzes the scattered light of different wavelength than the incident light to obtain the molecule structure of the analyte. When a incident laser light illuminate the sample, light collide material molecules and scatter. Most of the scattered light features the same wavelength with the incident light, only a very small amount scattered light( typically 0.0000001% ) at different wavelengths with incident light, which is inelastic scatter called Raman scatter. The scattered light frequency less than incident light is called Stokes scattering, the scattered light frequency bigger than incident light is called Anti-Stokes scattering, they are symmetrically distributed on both sides of the Rayleigh scattering.

라만 분광학의 원리: 입사광과 다른 파장의 산란광을 분석하여 분석 대상의 분자 구조를 파악하는 산란 기술입니다. 입사 광자가 분자와 충돌할 때 에너지 일부가 분자 진동으로 전달되어(라만 산란) 파장이 이동한 빛이 방출됩니다.
