MO Diagrams for Diatomic Molecules
www.chem.uci.eduHeteronuclear Diatomic Molecules: CO In molecules with more than one type of atom, MOs are formed from AOs that have different energies. Consider CO: 2sa 2pa C 2sb 2pb C≡O O σ σ* π π* σ σ* Bonding orbitals get polarized towards oxygen Anti-bonding orbitals get polarized towards carbon HOMO is on carbon LUMO is on carbon too!

web.gccaz.eduDiatomic Molecules: You should know the seven elements that exist as diatomic molecules: H 2 (g) N 2 (g) F 2 (g) O 2 (g) I 2 (s) Cl 2 (g) Br 2 (l) “Have no fear of ice cold beer” However these elements are not diatomic when they are in compounds, for example the correct formula for sodium chloride is NaCl not NaCl ...
Are Nitrogen Molecules Really Larger Than Oxygen …
www.getnitrogen.orgO2 and N2 are diatomic molecules (two atoms joined by a chemical bond or bonds), not spheres in shape but rather cylindrical in shape, akin to the shape of a tiny jelly bean. Thus, a "length" dimension of the cylindrical shape is a larger dimension than the smaller "waistline" diameter of the cylindrical shape. In transport
Molecular energy levels and spectroscopy
vallance.chem.ox.ac.ukDiatomic molecules are often approximated as rigid rotors, meaning that the bond length is assumed to be fixed. Solving the Schrodinger equation for a rigid rotor gives the following energy levels: E(J) = B J(J+1) In this equation, J is the quantum number for total rotational angular momentum, and B is the rotational
