Raman spectroscopy is an optical technique that detects intrinsic vibrational, rotational and other low-frequency modes in molecules upon inelastic scattering of monochromatic light. Because ...

However, this reduces the sensitivity of low-cost silicon CCD detectors at longer wavenumbers, making it difficult or impossible to view the "stretch" section of the Raman spectra (2000-4000 cm-1).

A Raman spectroscopy system uses a laser to illuminate a target sample and a spectrometer to detect inelastic light scattering. The scattered light is displaced in wavelength from the laser emission ...
