Representative Raman spectrum of drug crystals in wells for the investigation of drug polymorphism. (a) Indomethacin, (b) ketoprofen, (c) fenofibrate, (d) mefenamic acid, (e) ibuprofen, (f) aceclofenac, (g) naproxen, and (h) atenolol. Raman spectra of initial and recrystallized crystals are shown in blue and red, respectively. Each spectrum is normalized in intensity. Representative microscopic images of crystals are also shown for each drug molecule. The image size is 1.4 × 1.0 mm2.
