Modeling systems in chemistry

Lysozyme is a common enzyme present in tissues and secretions. It is one of the most studied proteins and has become an important model system in chemistry, en-zymology and immunology. It was discovered by Alexander Fleming in 1922 [59]... 

The binding forces in aggregates and clusters are often weak interactions of the van der Waals type. These van der Waals forces are responsible for important phenomena such as deviations from ideal gas behaviour, and the condensation of atoms and molecules into liquid and crystalline states. Such weakly bound van der Waals molecules have become model systems in chemistry. Both the stmcture and the photodissociation of van der Waals molecules are discussed later in some detail (see the examples in Part 6).
