Additionally, valence bond theory cannot explain electronic transitions and spectroscopic properties as effectively as MO theory. Furthermore, while VBT employs hybridization to explain bonding, it can oversimplify complex bonding situations, limiting its applicability in more intricate molecular geometries such as transition metal compounds.

Heitler and London's original work on VBT attempts to approximate the electronic wavefunction as a covalent combination of localized basis functions on the bonding atoms. [6] In VBT, wavefunctions are described as the sums and differences of VB determinants, which enforce the antisymmetric properties required by the Pauli exclusion principle.
VBT may refer to: Valence bond theory, one of two foundational theories of quantum chemistry; Vijñāna Bhairava Tantra, the text in Kashmir Shaivism;
A group of Republicans recently introduced a bill to repeal the Impoundment Control Act. It would hand Trump more control over government spending — he could even unilaterally cut it off.
Firefighters in the Bronx worked to save an apartment complex that caught on fire. Around 6 p.m. Wednesday, someone reported the fire, which had broken out at 3030 Heath Avenue in the Bronx, the ...
Experts explain whether ice or heat for back pain will lead to better relief, and the best time to use each.
Possible geometries for steric numbers of 10, 11, 12, or 14 are bicapped square antiprismatic (or bicapped dodecadeltahedral), octadecahedral, icosahedral, and bicapped hexagonal antiprismatic, respectively.
In theoretical chemistry and molecular physics, Coulson–Fischer theory provides a quantum mechanical description of the electronic structure of molecules. The 1949 seminal work of Coulson and Fischer [1] established a theory of molecular electronic structure which combines the strengths of the two rival theories which emerged soon after the advent of quantum chemistry - valence bond theory ...
