ENERGY-LEVELS OF THE WEAKLY INTERACTING RADICALS

Energy levels of the weakly interacting radicals are estimated on the basis of planar methyl radical interaction as a model. These levels de pend on the given separation r between the centers of mass. The approp riate Schrodinger equation is solved by using the Brillouin-Wigner ser ies method. Analytical forms for the integrals used to estimate matrix elements are derived. The principle of total momentum conservation is strictly obeyed. Some energy levels cannot be estimated as a result o f divergence.
