我们对红外和太赫兹范围内从振动激发的溶剂化双丙氨酸分子到周围水的能量流进行了比较研究。我们采用驱动分子动力学 (DMD) 方法来研究从溶质分子到水分子的能量流。因此,我们发现,与红外模式相比,激发太赫兹模式时,从溶质到水的能量流更加快速和有效。我们的结果显示了太赫兹范围内溶质的低频模式与水动力学的强耦合。相反,当激发溶质的红外模式时,我们发现更多的局部运动。
We present a comparative study of energy flow from a vibrationally excited solvated dialanine molecule to the surrounding water in the IR and THz range. We employ the driven molecular dynamics (DMD) approach to investigate the energy flow from the solute molecule to water molecules. As a result, we find a more rapid and efficient energy flow from the solute to the water when exciting THz modes compared to IR modes. Our results show a strong coupling of the low frequency mode of the solute and the water dynamics in the THz regime. In contrast, when exciting the IR modes of the solute, we find much more localized motions.
