A priori approximation of integral‐transform wavefunctions by Gauss quadrature provides an efficient and simple method for obtaining a finite approximation to the complete set of eigenfunctions of the Hamiltonian of a two‐electron atom. These fun

As the first step to the ab initio calculation of the vibration‐rotation spectrum of the H3+ ion, we present results of configuration‐interaction calculations of the potential‐energy surface and the geometry‐dependent electric dipole and quad

The classical orbits of a rotating Morse oscillator are calculated by means of Hamilton–Jacoby theory after truncating the Hamiltonian to permit analytical solution. Except at very high J, the approximate analytic orbit for the radial coordinate is
