The differentiation of polymorphs is important, particularly in the pharmaceutical industry. We demonstrate the practicality of using Raman spectroscopy to differentiate crystal forms for polymorph characterization and screening, and explain aspects of chemical bonding and solid state structure that affect the Raman spectra of crystal lattice vibrational modes.

Laser-induced breakdown spectroscopy (LIBS) has seen significant expanded adoption in recent years, particularly in industrial applications where it can provide important advantages over other techniques. Mohamad Sabsabi, of the National Research Council of Canada, has been leading programs to research and implement the use of LIBS in mining and energy applications.
