Abstract: | Both a quantum molecular dynamic method and high level ab initio calculations (MP2, CCSD(T)) havebeen used to investigate the mechanism of the C3 + H3+ reaction, which is part of the ionchemistry in interstellar clouds. Furthermore statistic initial orientations in collision simulationshave been set up in order to determinate reaction cross-sections and rate coefficients of all occurringreaction channels. Our analysis shows that the revealed mechanism isstrongly determined by dynamic effects. |
