本研究は、さまざまな温度で異なる濃度のLi$$^{+}$$及びMg$$^{2+}$$の陽イオンを含むD$$_{2}$$O中の水和電子の吸収スペクトルをパルスラジオリシスにより測定するとともに、量子古典分子動力学法(QCMD)シミュレーションを用いて吸収スペクトルのシフトの温度や塩濃度の依存性を解析した。

In this work, we measure the absorption spectra of hydrated electron in D$$_{2}$$O solutions containing different concentrations of Li$$^{+}$$ and Mg$$^{2+}$$ cations at various temperatures by pulse radiolysis techniques, and perform quantum classical molecular dynamics (QCMD) simulations to explain the shift of the absorption spectra due to the combined effects of temperature and salt concentration.
