Polymorphism is the ability of one material to exist in more than one crystal structure and can be found in any crystalline formation process including polymers, minerals and other chemical or biomedical reactions. Raman spectrometers are used to identify the crystals respectively by monitoring polymorph transitions at-line in pharmaceutical PAT applications for further process control without delay. In crystallography, Raman technology is also used to predict the orientation growing status through the ratio rate of Raman peak intensities in different positions.
