    摘要: A magnetic interaction is calculated by expressing a localized magnetic orbital as a linear combination of molecular orbitals and determining a localized magnetic orbital to be calculated from a maximum overlap condition evaluated between a reference orbital localized in anatomic orbital and the localized magnetic orbital. Another magnetic interaction is calculated by expressing a localized magnetic crystal orbital as a linear combination of crystal orbitals and determining a localized magnetic crystal orbital to be calculated from the maximum overlap condition.
