环Polymer分子动力学的化学反应速率:理论与实际应用

Chemical Reaction Rates from Ring Polymer Molecular Dynamics: Theory and Practical Applications

Yury V. Suleimanov, F. Javier Aoiz, Hua Guo

摘要:

这篇专题文章概述了环状聚合物分子动力学(RPMD)速率理论的现状。我们首先分析RPMD方法及其与量子过渡态理论的联系。然后,我们专注于它的实际应用,在气相中的原型化学反应,这表明如何准确和可靠的RPMD是计算热化学反应速率系数在各种情况下。这篇综述是RPMD速率理论发展的一个重要检查点,表明RPMD正在从仅仅是最近的一个新想法转变为一个成熟的和经过验证的替代传统技术来计算热化学速率系数。我们也希望这将促进RPMD在各种化学反应中的进一步应用。

英文摘要:

This Feature Article presents an overview of the current status of Ring Polymer Molecular Dynamics (RPMD) rate theory. We first analyze the RPMD approach and its connection to quantum transition-state theory. We then focus on its practical applications to prototypical chemical reactions in the gas phase, which demonstrate how accurate and reliable RPMD is for calculating thermal chemical reaction rate coefficients in multifarious cases. This review serves as an important checkpoint in RPMD rate theory development, which shows that RPMD is shifting from being just one of recent novel ideas to a well-established and validated alternative to conventional techniques for calculating thermal chemical rate coefficients. We also hope it will motivate further applications of RPMD to various chemical reactions.
