دانلود مقاله On the Origin of Covalent Bonding in Heavy Actinides

دسته بندی : مقاله های انگلیسی فایل : pdf تعداد صفحات : 10 رشته مقاله : شیمی زبان مقاله : انگلیسی مقدمه :Recent reports have suggested the late actinides participate in more covalent interactions than the earlier actinides, yet the origin of this shift in chemistry is not understood. This report considers the chemistry of actinide dipicolinate complexes to identify why covalent interactions become more prominent for heavy actinides. A modest increase in measured actinide: dipicolinate stabil ...
