Grasping complexity in chemical kinetics: top-down, bottum-up and some more

(a) Insight in the chemistry of the investigated process can be translated into so-called chemical rules. This can be implemented as algorithms in computer code, allowing the automatic generation of reaction networks consisting of several thousands of elementary steps. Databases, which are based either on experiments or on the quantum chemical calculation of model reactions, then provide the corresponding thermodynamic and kinetic parameters.
