Outline of Final Research Achievements |
Reaction dynamics of micro-solvated molecules have been investigated by means of direct ab-initio molecular dynamics (MD) method. The purposes of this study are to elucidate the dominant factor on the reaction mechanism in micro-solvated clusters, and the effects of micro-solvation on the product reaction channels. The reaction systems used in the present study were water cluster, hydrated DNA base pair, hydrated thymine dimer, and oxygen molecule. It was found that the micro-solvation enhances efficiently proton transfer reactions following the ionization.
