Laser techniques are used to enlarge the range of application of crossed‐beam experiments and to increase their resolution, via excitation of atomic/molecular reagents on well‐defined quantum states and characterization of reaction products by L.I.F. and R.E.M.P.I. Detailed applications are described in the case of the Cs + H 2 → CsH + H photochemical reaction for which a complete set of experimental data was obtained and interpreted by quasi‐classical trajectories. To apply these techniques precise spectroscopic data are required, which are obtained from high resolution, Doppler‐free beam experiments. In turn, reaction dynamics experiments provide out‐of‐equilibrium light sources which can be used to extend spectroscopic analyses. It is shown how the high resolution study of the TiO molecule leads to a new description of its electronic structure.
