%Nevertheless, %the spin-orbit interaction opens avoided crossings between low energy excited levels of opposite spin orientation and opposite spatial parity. For two-electrons the spin-orbit coupling allows for low-energy optical transitions that are otherwise forbidden by spin and parity selection ...
As we’ll see, it’s quite common for electrons to occupy antibonding states – albeit for brief periods of time – without the molecule being destroyed. Electrons are small (1/1840 the mass of a proton) and nuclei are heavy; an electron can zip up to an antibonding state and back down...
Bond electrons make up bonding molecular orbitals or BMOs. The electrons form a covalent linkage when they combine. On the other hand, antibonding molecular orbitals don’t contribute to bonding, and hence they are found located external to the bond. What are molecular orbitals? T...

And he coined the term covalentbonding. 他创造了共价键这一概念。 Avoid negativebonding. 回避消极的亲密。 These are thebondingand antibonding. 这是成键和反键。 It promotesbondingbetween individuals. 它增进个体间形成的亲密关系。 And there's weak hydrogenbondingbetween them. ...
In a better model the electrons are not considered independent and then the state is built over a linear combination of one-particle states and you can combine them as a+b or like a-b. One combination given bonding and other antibonding. I would not say interference of waves, but it is...
Thus, it is possible to measure quantitatively the relative bonding or antibonding character of actual molecular orbitals, relative to hypothetical nonbonding atomic orbitals, by using experimental valence and core ionization potentials. 展开 关键词: inorganic, organic, physical and analytical chemistry ...
