一定电偶极矩的刚性转子在电场中的能量

The Energy of A Rigid Rotor with A Certain Electric Dipole Moment in Electric Field

量子力学中用来求问题的近似解方法,通常是从简单问题的精确解出发来求较复杂问题的近似解.体系的哈密顿算符不是时间的显函数的情况,讨论的是定态问题.用定态微扰论计算,具有一定电偶极矩的刚性转子绕中心在一平面内转动,在转动平面内存在电场强度时能量的修正.

In quantum mechanics,it usually starts from the exact solution of simple problems to find the approximate solution of more complex problems.When the Hamiltonian operator of a system is not an explicit function of time,it is focused on problems of stationary state which is usually discussed.In this paper,a method of perturbation theory is used to calculate the corrected value of energy when a rigid rotor with a certain electric dipole moment rotates around the center in a plane with electric field intensity.
