Unformatted text preview: solu0ons to the wave equa0ons for molecules are difficult to find (e.g. dealing with e ­ ­e ­ interac0ons), but several methods of finding approximate solu0ons exist. Important similariBes between AO’s and MO’s: ⤷  Both can hold two electrons having opposite spins. ⤷  Pauli Exclusion Principle and Hund’s Rule apply. ⤷  The square of the MO wave func0on provides an indica0on of the electron probability. Recall From Valence Bond Theory When two hydrogen atoms are far apart, there is no interac0on of their atomic orbitals. As they become closer, the nucleus in one atom becomes a_racted to the electrons of the other atom. This a_rac0on causes electron density to accumulate between the nuclei of the two atoms (localized). The two atoms have reached the op0mum internuclear distance (op0mum bond length) when electron ­nuclear a_rac0on is...
