| Research Abstract |
Fragmentation paths through fast hydrogen migration within ionized organic molecules by an intense femtosecond laser field were investigated based on measured ion yields and results of the quantum chemical calculation. The H_3O^+ ejection paths via C_2H_4OH^+ for ethers and alcohols, and via C_2H_5OH_2^+ for ethanol dimer, and their time scales were clarified. In the experiment using deuterium-labeled ethane, CH_3CD_3, it was demonstrated from H/D mixing ratios in the H_2^+,H_3^+,H_2 fragments that a reaction path through a CH_2CH_2^<2+>…H_2 complex produces H_2 and H_3^+ fragments.
