The … WebSep 1, 2024 · See the normalized Gaussian and Lorentzian Raman peak profiles in Figure 1. The most significant differences between these line shapes appear below the full width at half-maximum (fwhm) of the peak. Here, you see a significant broadening of the edges of the Lorentzian profile compared to those of the Gaussian profile.
