In this project in the Theoretical and Computational Chemistry Program of the Chemistry Division, Professor McCurdy plans to investigate what happens when electrons collide with molecules, as well as what happens to atoms when they are placed in stong electric or magnetic fields. A range of studies (including electronic excitation, dissociation, and vibrational excitation by electron impact) of collisions of electrons with polyatomic molecules will be performed on small polyatomic molecules. The investigations will be based on the complex Kohn variational approach, and the efforts will be focused on intrinsically polyatomic phenomena and on systems which are important for plasma applications. The same computational methods will be used to study the dynamics of atoms in intense fields, where the field destroys the symmetry of the atomic problem.

在这个理论与计算化学的项目中， 化学系的课程，麦柯迪教授计划 研究当电子与分子碰撞时会发生什么， 以及原子在强磁场中的变化 电场或磁场。 一系列研究（包括电子激发， 解离和电子碰撞的振动激发） 电子与多原子分子的碰撞 在小的多原子分子上进行。 调查 将基于复杂的科恩变分方法，和 我们的工作将集中在本质上的多原子现象上 以及对等离子体应用很重要的系统。 同样的计算方法将用于研究 原子在强磁场中的动力学， 原子问题的对称性
