Foundations of Hadronic Chemistry: With Applications to New Clean Energies and Fuels

Regardless of striking achievements, Quantum Chemistry has did not in achieving unique representations of molecular facts from distinctive quantum rules. Hadronic Chemistry is a brand new, nonlinear, nonlocal and nonunitary overlaying self-discipline which admits all quantum versions as specific circumstances, whereas allowing invariant representations of molecular facts certain to any wanted accuracy.
