9316608 Lasaga该奖项将支持地球化学过程的原子描述以及地球化学和岩石学动力学理论的发展方面的持续理论和实验工作。 该研究将继续获得重要地球化学气体分子、硅酸盐、铝硅酸盐和其他矿物中键合的高质量量子力学信息。 量子力学的结果将被纳入势能函数，然后在动力学研究的反应速率，估计动力学同位素效应，分子动力学和蒙特卡洛模拟。 这些研究将阐明原子物理学与地球科学家感兴趣的宏观热力学和动力学现象之间的关系。

9316608 Lasaga This award will support continuing theoretical and experimental work on the atomic descriptions of geochemical processes and the development of kinetic theory in geochemistry and petrology. The research will continue the task of obtaining high quality quantum mechanical information on bonding in important geochemical gas molecules, silicates, aluminosilicates and other minerals. The quantum mechanical results will be incorporated into potential energy functions, which are then employed in kinetic studies of reaction rates, estimates of kinetic isotopic effects, molecular dynamics and monte carlo simulations. These studies will elucidate the relationship between atomic physics and macroscopic thermodynamic and kinetic phenomena of interest to earth scientists.
