Webcrystallinity than the good material. From both sets of data, it appears that the final degree of crystallinity in the bad material is about 50% higher than the good. In both cases, the final degree of crystallinity is much lower than in the starting materials. DSC-Raman spectroscopy allows us to precisely probe the WebRaman spectra. We graphically depict the results of our measurements as Raman spectra. We plot the intensity of the scattered light (y-axis) for each energy (frequency) of light (x-axis). The frequency is traditionally measured in a unit called the wavenumber (number of waves per cm, cm -1 ). We plot the x-axis frequencies relative to that of ...
