By using the methods of perturbation theory it is possible to construct simple formulae for the numerical integration of the Schrodinger equation, and also to calculate expectation values solely by means of simple eigenvalue calculations. 1. The basic theory may be a multiplicative operator instead

An algorithm to solve the two-dimensional Schrodinger equation based on the finite-element method is proposed. In our scheme, the molecular Hamiltonian with any arbitrary internal coordinate system can be solved as easily as with the Cartesian coordinate system. The efficient computer program based
A new sixth-order Runge-Kutta type method is developed for the numerical integration of the one-dimensional Schrodinger equation. The formula developed contains certain free parameters which allows it to be fitted automatically to exponential functions. We give a comparative error analysis with othe
Recently an interesting new class of PDE integrators, multisymplectic schemes, has been introduced for solving systems possessing a certain multisymplectic structure. Some of the characteristic features of the method are its local nature (independent of boundary conditions) and an equal treatment of
