Rayleigh spectroscopy
WebPrinciple Basics. The Raman effect is based on the scattering of light, which consists of elastic scattering at the same wavelength as the incident light and inelastic light at different wavelengths due to molecular vibrations. The elastic scattering is Rayleigh scattering and inelastic scattering is Raman scattering. WebThe Brillouin spectra of 6 M guanidine hydrochloride have been found to contain an additional component in Rayleigh scattering that manifests itself as a broad quasi‐elastic scattering line ...

Web(1) In Raman spectroscopy Rayleigh scatter will be a thousand times more intense and needs to be rejected instrumentally. (2) Raman spectroscopy is difficult in the presence of a fluorophore concentration greater than nanomolar. (3) Rayleigh and Raman scatter from the solvent will make fluorescence measurements difficult below nanomolar ... WebB.

WebThe irradiated light interacts with the molecule and only a part of its wavelength is scattered ( known as Raman scattering) In Raman or Rayleigh scattering the irradiation of the light … WebBlocking Rayleigh Scattering. In order to obtain high signal-to-noise in Raman measurements, it is necessary to block Rayleigh scattering from reaching the detector while transmitting the Raman signal. It's possible to use a double or triple grating spectrometer to accomplish rejection of the background signal.
