Non-lineal equations for the Raman spectroscopy analysis

Abstract

We study some equations used in the analysis of the materials of the Raman spectrum. Some equations are, phonon lifetime, related to the full width at half maximum (FWHM), the size of the nanoparticles, as explained with the equation of the intensity of Raman Spectrum; the Grüneisen parameter isothermal and isobaric explained by the frequency shift of the Raman scattered light; it is directly related to the structural properties of the material. The frequency shift may be dependent upon the application of temperature, hydrostatic pressure and the composition of the material itself. Furthermore, it is possible to obtain the behavior of anharmonic material using the Raman scattering frequency shift. © Published under licence by IOP Publishing Ltd.
