Solid state dynamic behaviour of organic molecules

The main interactions characterizing the crystals of organic molecules are weak interactions such as hydrogen bonds, van der Waals forces, hydrophobic interactions, etc.1 Considering the weak nature of the forces involved, the crystals subjected to specific treatments such as heat treatments, tend to suffer dramatic consequences such as the loss of crystallinity of the material. In some cases, solid-to-solid crystallization processes, induced by heat treatment, have been recently demonstrated. However, due to the complexity and the instability of organic crystals, the solid-to-solid crystallization process of organic molecules is still poorly understood. For this reason, understanding what are the effects that external stimuli induce on crystals and powders of organic molecules is fundamental. .. [edited by Author]
