1 Introduction A core aspect of coarse graph theory is to identify geometric properties of (typically connected, infinite) graphs which are preserved by a large-scale geometric generalisation of graph isomorphism known as quasi-isometry, and use these properties to distinguish classes of graphs.

Thus, the well-known white phosphorus breaks into two P 2 units at elevated temperatures, (1) because the 2P 2 → P 4 process is a thermodynamically spontaneous reaction. In contrast, the ubiquitous noncovalent intermolecular interactions have been regarded as less important for chemical reactions.
