Astrochemistry
Project goals
Explanation of some astronomic problems needs expertise of chemists and the Action CM0805 should be helpful in this respect. Chemical reactions in cosmos proceed differently from those in the Earth atmosphere because of low or high temperature, low pressure and exposure to radiation of different kind. Both laboratories engaged in the project claim techniques by which these off-terrestrial conditions can be simulated and the chemical reactions so affected modelled.

Project results evaluation
We developed methods and tools for an efficient computations of low-energy collisions of electrons with diatomics and polyatomic molecules. We explained an anomalous behavior of cross sections for nitrogen molecules. In the laboratory of the co-investigator we have measured binary and ternary rate constants of H3+ ion recombination as a function of the nuclear spin state. These results are unique.
