Crystallographic models
WebThe crystallographic theories can be classified into two main groups: Taylor models and self-consistent models. Section 2.1 will review the Taylor models and briefly ad dress the self-consistent models. Space-filling models arise out of a desire to represent molecules in ways that reflect the electronic surfaces that molecules present, that dictate how they interact, one with another (or with surfaces, or macromolecules such as enzymes, etc.). Crystallographic data are the starting point for understanding static molecular structure, and these data contain the information rigorously re…
