Molecular rotations. In this chapter, we look at the quantum-theoretical description of rotational motion. This is relevant for modeling molecules tumbling in the gas phase (but not in the liquid or solid state).

14 Αυγ 2024 · In atoms, there are a total of four quantum numbers: the principal quantum number (n), the orbital angular momentum quantum number (l), the magnetic quantum number (m l), and the electron spin quantum number (m s). The principal quantum number, \(n\), describes the energy of an electron and the most probable distance of the electron from the ...
17 Αυγ 2006 · This paper discusses recent progress that has been made in the understanding of the electronic structure and bonding situation of carbon monoxide which was analyzed using modern quantum chemical methods.
21 Απρ 2022 · Use the frequency of the \(J = 0\) to \(J = 1\) transition observed for carbon monoxide to determine a bond length for carbon monoxide.
Responsible for the dipole moment is the highest occupied molecular orbital, a $\pmb{\sigma}$ orbital, which has its largest coefficient at the carbon atom. In first order approximation, this orbital can be considered the lone pair of carbon.
16 Μαΐ 2016 · Point out key differences between the diagrams and use the diagram to explain why $\ce{CO}$ acts as a two-electron donor through carbon rather than through oxygen. Understandably, the key difference between these molecules is that $\ce{CO}$ is heteronuclear, and thus will have differences in energy between the molecular orbital and the atoms.
Describing the electronic structure of, and the nature of the bond in, carbon monoxide in terms of simple bonding models is not a trivial task because of the unusual chemical and physical proper-ties of the molecule, the only monocoordinated carbon compound that is stable under normal conditions.
