Webb4 juli 2015 · Quenching is a process involving rapid cooling in quenching media and hardening of steels. The effect of quenching process on the microstructure and … The Stern–Volmer relationship, named after Otto Stern and Max Volmer, allows the kinetics of a photophysical intermolecular deactivation process to be explored. Processes such as fluorescence and phosphorescence are examples of intramolecular deactivation processes. An intermolecular deactivation is where the presence of another chemical species can accelerate the decay rate of a chemical in its excited state. In general, this process can be repres…
