    Subunit: Crystallization and characterization of solid phases and polymorphs

    This subunit is devoted to crystallization techniques and to the corresponding structural characterization: determination of the crystal structure and of the absolute molecular conformation, singling out and definition of polymorphic, hydrated or solvated forms.

    (Prof. Alessia Bacchi:)
    Crystallization and characterization of molecular structure and crystalline form of drugs with reference to the individuation of polymorphs, solvate and co-crystals. Techniques of X-ray diffraction on single crystal and on powders, also at non-ambient conditions.

    (Prof. Alberto Girlando)
    Characterization of organic molecular crystals, with different optical spectroscopy methods. Particular expertise is on micro-Raman spectroscopy in the Tera-Hertz spectral region for the quick identification of polymorphs, also as a function of temperature or high pressure.
