Preferred Label : spin-statistical factor;
Detailed label : spin-statistical factor (in diffusion-controlled reactions);
IUPAC definition : From the possible encounter pairs between states of different spin multiplicity, only
those conserving multiplicity in going to products are expected to react.;
Scope note : this factor determines the efficiency of diffusion-controlled reactions, which have
an encounter-controlled rate. typical examples are quenching of fluorescence of aromatic
hydrocarbons by o2 , quenching of triplet states by
o2 , and triplet–triplet annihilation.;
Origin ID : ST07482;
