Molecular anatomy revealed: CT scans for molecules show the gauzy nature of matter

Another widely applied model, called the molecular orbital (MO) theory, eases those computations, but only by including hard-to-visualize concepts such as bonding electronic orbitals that aren't confined between bonded atoms.

Stretching conceptions of chemical bonds

Had Kekule known in his time about quantum theory's concept of molecular orbitals introduced in the late 1920s, he would have melted his two structures into what is now called a "resonance hybrid." Molecular orbital theory, which accounts for chemical bonding by describing where electrons are likely to be found around a molecule, is presented in today's general chemistry courses as a modern refinement of Kekule's valence bond theory, which describes how electrons localized around atoms interact to form bonds.
