Outline of Final Research Achievements

We developed a theory and its software to analyze compounds under strong magnetic field. The quantum-chemical calculations of NMR chemical shifts are main objective in this research. We presented a gauge-independent relativistic quantum-chemical method, and higher-order relativistic magnetic term, and developed basis-functions for molecules in strong magnetic field.
Further, we developed a software to calculated accurately and illustrate the electron spin density of diamagnetic molecules in strong magnetic field, incorporated with the generalized unrestricted Hartree-Fock method.
