    • Throughout this paper, we adhere strictly to the requirement that polymorphic forms have identical chemical composition: in the case of molecular crystals, they must contain the same type(s) of molecule(s) with the same stoichiometry. A given type of molecule may exist in different crystalline phases, such as (i) "pure" crystals containing only the given type of molecule or (ii) cocrystals containing the given type of molecule and one or more other types of molecule (which encompasses also solvate phases in which the "other molecule" is the solvent used in crystal growth). Crystalline phases within a given category, provided they have the same chemical composition, may be classified as polymorphic forms. Crystalline phases in different categories cannot be classified as polymorphic forms. We note that the present paper considers only crystalline phases of the type covered by category (i).

    • These experiments have so far been carried out for the α and γ polymorphs, as these polymorphic forms are generally easier to prepare as monophasic samples in large quantities.
