Raman spectroscopy fundamentals. Learn about Raman vs IR, Raman scattering principle, the Raman shift, Rayleigh scattering and more.
The present invention addresses the problem of reducing noise generated by scattering of excitation light in a Raman spectroscopy analysis apparatus for detecting Raman-scattered light emitted from a sample circulating inside a measurement chamber. Provided is a Raman spectroscopy analysis apparatus (300)...
Raman spectroscopy is a highly selective and non-destructive optical spectroscopy technique which relies on the inelastic scattering of laser light to probe molecular structure. The non-destructive nature of Raman measurements along with the molecular specificity of the spectra make it an optimal techniqu...
Precision engineered Raman spectrometers for fast and accurate chemical analysis. What is Raman spectroscopy? Raman spectroscopy is a form of vibrational spectroscopy, like infrared (IR) absorption, that provides detailed chemical and structural characterisation. The Raman technique has the benefit of being...
By comparing the spectral response of each spectrometer for ‘lamp on’ and ‘lamp off’ we can determine the amount of stray light in each design when configured for Raman spectroscopy. A‘lower bound’ and ‘upper bound’ spectral region is chosen for the analysis. The lower bound in each...

In this study Raman spectroscopy was used to identify and quantitate puerarin, an isoflavone present in the traditional Chinese medicine Radix puerariae. Information was obtained about puerarin's molecular structure, and a quantitative model was established using a linear relationship between the ratio of...
This paper presents work towards a gas sensor based on surface enhanced Raman spectroscopy (SERS). Sensitive SERS analysis of CO and N2O was performed using a mixed AgPd nanoparticle substrate that facilitated effective gas adsorption and strong SERS generation. The adsorption, desorption and displacem...
