Study of fast reactions
1) Continuous flow method
The complexation reaction between Fe2+ and thiocyanate, SCN–, in aqueous solution.
Stopped-Flow
measurements in real time not requiring large amounts of reagents (as little as 1 cm3 may be sufficient) the time resolution is a little faster then for continuous flow.

Molecular Beams
state-to-state reactive scattering in crossed molecular beams reaction. stereodynamics with aligned reagents: clusters and crossed beams
How can we control the state of a molecule?
Electronic state (absorption and emission of UV-vis light )
heating and cooling using laser?
Vibrational state (absorption and emission IR)
Rotational state (magnetic control)
Transitional state (speed selection)
