Then, the changes of the geometrical structures and the energies of the stationary points were analyzed by using the intrinsic reaction coordinate ( IRC) method. Zero-point energy correction has been done along the minimum energy path ( MEP) for each reaction. 然后依据反应途径的内禀反应坐标(IRC)理论,计算并分析了IRC途径上各驻点分子结构的变化和能量的变化,对沿反应最小能量途径的一系列驻点进行了零点能校正;
To gain more accurate potential energy surface, single point energies of all the species and the selected points along the minimum energy path are refined at the QCISD ( T) level. 为获得更为准确的反应势能面信息,采用高水平QCISD(T)方法对各驻点及反应路径上选择点进行了单点能校正。
The algorithm given in this paper inherits the basic idea of potential energy field method. By searching the minimum value of the energy function, the collision free path can be found. 算法继承了人工势场法的基本思想,通过寻找路径点的能量函数的极小值点而使路径避开障碍物。
The optimized geometries, frequencies and minimum energy path ( MEP) is obtained at the BH& H-LYP/ 6-311G ( 2d, 2p) level, and energetic information is further refined at the MC-QCISD ( single-point) level. 在BH&H-LYP/6-311G(2d,2p)水平下获得了优化几何构型、频率及最小能量路径(MEP),能量信息的进一步确认在MC-QCISD(单点)水平下完成。
Vibration analysis is carried out to confirm its identity as a transition structure. The intrinsic reaction coordinate is performed to search the minimum energy path. 通过优化计算找到了反应的过渡态,且振动分析确认了过渡态的结构,并用内禀反应坐标方法确定了能量最低反应路径。
We first study Min-power Single source h-Multicast where the task is to find a minimum energy multicast tree in which the path between the source and every destination node is less than h hops. 首先研究最小能量单源h-组播,即找到一颗能量代价最小的组播树,要求在组播树中从源节点到任一个目标节点均存在一条长度不超过h的路径。
