WebbA Raman spectrum (Figure 6) is defined by plotting the intensity of this “shifted” light versus frequency results in a Raman spectrum of the sample. Generally, Raman spectra are plotted with respect to the laser frequency such that the Rayleigh band lies at 0 cm-1. On this scale, the band positions will lie at frequencies that Webb1 sep. 2024 · The Raman spectrometer must have the spectral resolution sufficient to resolve the smallest differences in energies of the crystal lattice vibrational modes; these are affected by changes in molecular interactions arising from different unit cell structures or configurations of the molecules or formula units within the unit cell.
