Control of Chemical Reactions through Rectification of the Lorentz Force
Lasers can be used to manipulate atomic motions, breaking bonds and controlling reactions, making it possible to
explore new materials and to unravel new processes in chemistry and biology. The control of the rate of certain
chemical reactions by resonant laser excitation of selected vibrational modes has served as an important branch of photochemistry.

Ab Initio Study of Coherent Anti-Stokes Raman Scattering (CARS) of the 1,3,5-Trinitro-1,3,5-Triazacyclohexane (RDX) Explosion Molecule. Advances in coherent anti-Stokes Raman scattering (CARS)over the recent years have turned thistechnique into a unique and powerful tool used worldwide to probe structure and function of molecular or composite materials in biology. In the biomedical area, CARS detection makes it is possible to extend imaging of plant cells and tissue and provides exciting possibilities to gain information on processes at the microscopic scale. CARS microscopy is also expected to have potential applications in the field of stand off-detection of foreign substances in gaseous form or in interaction with substrates. Operation at ultra-low intensities is most often required in order to detect single molecules or microscopic objects for which the basic Raman cross section generally is very small.

The department of Theoretical Chemistry was established at KTH in 1999. We
are located at the Albanova University Center
- please come and see us! Our work is computer based, and
consists mostly of the modeling of microscopic systems - that is we use mathematical
models to simulate such systems in order to describe their properties, spectra
and reactions. This could mean a molecule, a cluster, a polymer, a segment of
a protein, a functional center in an enzyme, or a species which is dissolved in
a solvent or adsorbed on a surface. The modelling is mostly, but not always, based
on theories related to quantum mechanics. We have common projects among ourselves
and with other biologists, chemists and physicists, here and elsewhere. We are
also involved in teaching and seminars. If you want to learn more about us just
