借助当今改进的计算机,科学家可以获得势能梯度。通过在每个数值积分步骤求解与时间无关的薛定谔方程来得到经典轨迹。这种方法(称为直接动力学模拟)的实用性通过使用线性缩放和半经验电子结构方法而得到增强。
With today's improved computers, scientists can obtain the potential energy gradient for. a classical trajectory by solving the time-independent Schrodinger equation at each numerical integration step. The practicality of this approach-called a direct dynamics simulation-is enhanced by its use of linear scaling and semiempirical electronic structure methods.
