Raman shift vs wavenumber
Did you know?
WebbA Raman spectrum plotted on a wavelength scale would be very narrow and clustered. Wavenumber is very convenient since it also allows IR spectrum to be compared and is … WebbThis phenomenon was also observed in our Raman measurement of n-Ge samples, as shown in Fig. 3 (a). After the CWLA, a shift in the Raman peak toward a lower wavenumber was also clearly observed with our n-Ge samples and peak broadening was also observed on the Raman spectra, which indicates the substitution of the dopant into the Ge films.
WebbThe Raman Shift Calculator allows you to convert a known absolute wavelength to a Raman shift in wavenumbers, or to convert a known Raman shift in wavenumbers to an … WebbThe Raman shift is usually expressed in wavenumber and represents the energy difference between the incident photon energy and the inelastically scattered photon energy. Unlike …
