M . Zhang has proved from CASSCF ( 8, 8 ) that the quadruple bond based Molecular orbital theory is also reasonable.
32.
All bonds can be explained by resonance, and molecular orbital theory which includes linear combination of atomic orbitals and ligand field theory.
33.
On the other hand, an analysis within quantitative molecular orbital theory shows that 2-orbital-4-electron ( steric ) repulsions are dominant over hyperconjugation.
34.
However, the later edition in 1959 failed to adequately address the problems that appeared to be better understood by molecular orbital theory.
35.
:It sounds like a bastardization of the atomic orbital theory . " e-mail ) 07 : 20, 15 February 2007 ( UTC)
36.
Bonding usually discussed in the context of molecular orbital theory, which recognizes the triple bond as arising from overlap of s and p orbitals.
37.
The model determined by molecular orbital theory indicates that the bonds between boron and the terminal hydrogen atoms are conventional 2-center, 2-electron covalent bonds.
38.
More sophisticated models embrace covalency, and this approach is described by ligand field theory ( LFT ) and Molecular orbital theory ( MO ).
39.
They can be represented by orbitals of sigma and pi symmetry similar to molecular orbital theory or by equivalent orbitals similar to VSEPR theory.
40.
Due to their elegance and simplicity, the Woodward Hoffmann rules are credited with first exemplifying the power of molecular orbital theory to experimental chemists.
