Raman spectroscopy with variable temperature accessories has been valuable for probing phase transitions within solid-state pharmaceutical samples. In combination with other techniques [x-ray diffractometry, solid-state nuclear magnetic resonance (NMR), FTIR spectroscopy, and thermal analysis], the molecular basis for thermal transitions between dihydrates of carbamazepine prepared from different polymorphs of the drug were re-... 

The polymers included in this study are bisphenol-A polycarbonate (Bis-A PC), polyesteicarbonates (PEC), whose structures are defined in Figure 1, phenolphthalein bisphenol-A copolycarbonate, and polysulfone. All samples were compression molded and physically aged as described elsewhere, with the exception of those for the Fourier transform infrared (FTIR) measurements and solid state variable temperature nuclear magnetic resonance (VTNMR)...
