M . Zhang has proved from CASSCF ( 8, 8 ) that the quadruple bond based Molecular orbital theory is also reasonable.
22.
However, the later edition in 1959 failed to adequately address the problems that appeared to be better understood by molecular orbital theory.
23.
They can be represented by orbitals of sigma and pi symmetry similar to molecular orbital theory or by equivalent orbitals similar to VSEPR theory.
24.
Molecular orbital theory predicts two low-lying excited singlet states, denoted by the molecular term symbols 1 ? g and 1 ?.
25.
An analysis within quantitative molecular orbital theory shows that 2-orbital-4-electron ( steric ) repulsions are dominant over hyperconjugation.
26.
His work in the 1970s includes contributions on metal carbonyl complexes, metal carbonyl radicals, molecular orbital theory, and Nuclear quadrupole resonance.
27.
Bonding usually discussed in the context of molecular orbital theory, which recognizes the triple bond as arising from overlap of s and p orbitals.
28.
More sophisticated models embrace covalency, and this approach is described by ligand field theory ( LFT ) and Molecular orbital theory ( MO ).
29.
One important aspect of molecular physics is that the essential atomic orbital theory in the field of atomic physics expands to the molecular orbital theory.
30.
Due to their elegance and simplicity, the Woodward Hoffmann rules are credited with first exemplifying the power of molecular orbital theory to experimental chemists.
