Polymorphic Identification Using Raman Microscopy

Polymorphic Identification Using Raman Microscopy

Polymorphism is common in all organic molecules, forming more than one unique crystalline forms called polymorphs. This phenomenon is gaining traction especially in the pharmaceutical industry owing to the fact that a compound’s different polymorphs exhibit different physical and chemical properties, including bioavailability, dissolution rate, and thermal stability.

Density Mapping of a Poly(ethylene terephthalate) Film with the RamanRxn1™ Microprobe from Kaiser Optical Systems

Density Mapping of a Poly(ethylene terephthalate) Film with the RamanRxn1™ Microprobe from Kaiser Optical Systems

The detailed morphology of a polymer product, i.e., the degree of orientation and the level of crystallinity of the polymer molecules, greatly affects its physical properties. Crystallinity of a polymer refers to what proportion of polymer molecules are structurally ordered into 3D lattices, whereas orientation describes the degree of alignment of the polymer chains in a particular plane or axis.
