Preferred Label : quenching;
IUPAC definition : deactivation of an excited molecular entity intermolecularly by an external environmental
influence (such as a quencher) or intramolecularly by a substituent through a non-radiative
process.;
Scope note : when the environmental influence inhibits the excited state formation the process
is referred to as static quenching.; when the external environmental influence (quencher) interferes with the behaviour
of the excited state after its formation, the process is referred to as dynamic quenching.
common mechanisms include energy transfer, electron transfer, etc.;
