Thus the difference between localized and delocalized π-electron energies in the two models is closely similar. In the MO description of a Kekulé structure, negative π -bond orders appear across the formally ‘single’ bonds.

Chapter 7 Covalent Bonding and Molecular Orbitals

Chemical Data Analysis in the Large, The problem of localized versus delocalized bonding is almost as old as chemical structure theory itself. The first localized structures were probably drawn by A. S. Couper in 1859 in Ann. Chim. [1] and by Kekulé in 1860 in his famous “Lehrbuch der Organischen Chemie”. [3] The latter formulae are known as “Wurstformel” (sausage formula). Only a

Covalent Bonding and Molecular Orbitals Some seventy years ago, the physicist I! A. M Dirac declared-with no small degree of overstatement-that the whole of chemistry had been reduced to a solvedproblem: that the explanation of all things chemical lay in theSchrodinger equation and its solutions, and that chemists needed only to do the calculations. Chemists today are still doing those

From our study of chemical bonding so far Valence Bond Theory

As far as the strained small-ring compounds it appears the bending of a bond is a function of where one decides to draw the line between localized and delocalized character. Finally, no more appropriate ending could be contrived than a classic quote by Professor R. S. Mulliken ( 37 ), "I believe the chemical bond is not so simple as some people seem to think."

Localized and Delocalized Wave Functions for Butadiene

1/07/2014 · The delocalized proton becomes localized on either Glu-194 or Glu-204, and this is the prerequisite to open the Ser-193 gate. In other words, a localized proton in the BR ground state would open the Ser-193 gate too early and prevent proton pumping. The internal water cluster would merge with bulk water, and the proton would be released in a classical Grotthuss proton transfer to the bulk
