Flash photolysis
Flash photolysis is a
flash lamp. This first strong pulse is called the pump pulse and starts a chemical reaction or leads to an increased population for energy levels other than the ground state within a sample of atoms or molecules.[1]
Typically the absorption of light by the sample is recorded within short time intervals (by a so-called test or probe pulses) to monitor relaxation or reaction processes initiated by the pump pulse.
Flash photolysis was developed shortly after
in plants, signaling, and light-induced conformational changes in biological systems.See also
