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)
