“…4,29,37,43,50,53 -57,64,65,68 -71 Thus, numerous 2D correlation spectroscopy studies have been reported for concentration-or composition-dependent spectral variations of proteins, 29,43,50,57,70 polymers 37,53,54,56,64,65,68,69,71 and multicomponent mixtures. 4,55 For example, systematic studies of polymer blends and copolymers exhibiting specific interactions of components using 2D IR, 2D NIR, 2D Raman and hetero-correlation analysis have been reported.…”

“…Figure 49(a) and (b) shows FT-Raman and NIR spectra of PMMA and its blends with PVPh of contents 5 and 10 wt% in the ranges of 1770-1570 cm 1 and 7500-6500 cm 1 , respectively. 71 In these regions key bands for the specific interactions in the partially miscible blends may be observed. A Raman band at 1729 cm 1 is due to the free CDO stretching mode of PMMA, and a band at 1614 cm 1 , whose intensity increases with the increase in the PVPh content, is readily assigned to the aromatic ring stretching mode of PVPh.…”
