Rayleigh spectroscopy
WebThe depolarized Rayleigh light scattering spectra of pure polyethylene clycols and their solutions in an optically isotropic solvent were studied as a function of polymer molecular weight, concentration and temperature. Reorientational relaxation times were obtained by fitting the observed spectra to Lorentzian WebRayleigh scattering spectroscopy isalso well suited for combination with other experimental techniques for thecharacterization of individual nanotubes. This possibility is illustrated …

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.
