Preferred Label : pre-association;
IUPAC definition : A step on the reaction path of some stepwise reactions in which the molecular entity
C is already present in an encounter pair or encounter complex with A during the formation
of B from A, e.g. In this mechanism the chemical species C may but does not necessarily
assist the formation of B from A, which may itself be a bimolecular reaction with
some other reagent. Pre-association is important when B is too short-lived to permit
B and C to come together by diffusion.;
