Crystallographic axis orientation of 2-cyano-3-(3,4-methylene dioxy phenyl)-2-propenoic acid ethyl ester (CMPE) in a glass capillary with a 10-µm-diameter core was successfully clarified by polarizing microscopic Raman scattering spectroscopy. Polymorphic crystals of CMPE could also be distinguished in the glass capillaries by use of this method.
