Figure 13.
Comparison between Raman spectra of the XIBP = 0.8 blend taken at −100 °C just after cryomilling and after a first heating ramp up to 100 °C (a) in the low-frequency region, (b) in the C=O stretching region; the arrow localizes the Raman band distinctive of the H-bond network of IBP. These spectra are compared with those of glassy IBP at the same temperature.
