Polymorphism of glycine - Thermodynamic aspects. Part I. Relative stability of the polymorphs

The contribution summarizes the results of a systematic study of the three glycine polymorphs (alpha, beta, gamma-forms), including: i) the controlled crystallization of a desirable form, ii) a comparative calorimetric study of the three forms in the temperature range between 5 K and the sublimation temperatures (approximate to500 K).
