Nowadays, in modern quantum chemistry, such strong interactions are rather well understood and became an indispensable tool for all fields of chemistry. However, the description of weak interactions between atoms and molecules, which are responsible for the characteristics of the solid state, mostly remain unsolved and therefore attract considerable attention. Newly emerging technologies like nanotechnology, biotechnology and supramolecular chemistry urgently need a deeper understanding and more accurate description of weak intra- and intermolecular interactions. In recent years, theoretical chemistry has contributed efficiently to the desired knowledge, as demonstrated by the rapidly increasing number of papers in computational chemistry on this topic. Various methods are available for computations, whereas the development, assessment and combinations of these methods are in the center of this presentation. The computational applications are manifold, they range from the intermolecular interactions between molecules [1-3] to molecular arrangements on surfaces [4-6] and in molecular crystals [7-10]. Here, we concentrate on the last subject and its implications to the recent blind test of organic crystal structure prediction methods.[11]
