Preferred Label : encounter complex;
IUPAC definition : A complex of molecular entities produced at an encounter-controlled rate, and which
occurs as an intermediate in a reaction mechanism. When the complex is formed from
two molecular entities it is called an 'encounter pair'. A distinction between encounter
pairs and (larger) encounter complexes may be relevant in some cases, e.g. for mechanisms
involving pre-association.;
