  • Method and apparatus for evaluating molecular structures using relativistic integral equations
    Patent number: 5777889
    Abstract: An improved method of evaluating molecular structures using relativistic integral equations. The method transforms Cartesian non-relativistic integrals into relativistic integrals using a two-step process. A first step transforms two indecises of the non-relativistic integral equations into a plurality of intermediate equations. A second step transforms the plurality of intermediate set of integrals into relativistic integral. The relativistic integrals are then used to evaluate the relativistic behavior of the molecular structure.
