CHEMICAL REACTIONS AND LASERS: ELEMENTARY STEPS AND COMPLEX SYSTEMS

Article abstract of DOI:10.1016/0584-8539(90)80172-U

In recent years, various methods have been developed to observe and influence the course of chemical reactions using laser radiation.By selectively increasing the translational, rotational, and vibrational energies of the reaction partners with high intensity visible and UV lasers, direct insight can be gained into the molecular course of the breaking and the re-forming of chemical bonds.The production of free radicals by laser radiation can be used in chemical synthesis for the production of monomers.As example the kinetics of the UV-laser induced dehydrochlorination of CH3CClF2 is described.The application of linear and non-linear laser spectroscopic methods allows a non-intrusive observation of the interaction of transport processes with chemical reactions used with high temporal, spectral and spatial resolution.As a simple test system the ignition of O2-O3 mixtures by irradiation with a CO2 laser along the axis of a cylindrical vessel is considered.Mathematical simulation of the ignition process is simulated mathematically by solving the corresponding system of conservation equations.Experimental data are presented for velocity components of the flame front from IR-UV double resonance experiments and for the temperature history from infrared absorption measurements using tuneable diode lasers.
