Molecular Structure

  • Sune Svanberg
Part of the Springer Series on Atoms + Plasmas book series (SSAOPP, volume 6)


A molecule is formed by the binding of two or more atoms in such a way that the total energy is lower than the sum of the energies of the constituents. The bonds are normally of ionic or covalent nature. Particularly weak bonds occur in van der Waals molecules. The energy-level diagrams of molecules are significantly more complicated than those of atoms since, apart from energy levels corresponding to different electronic arrangements, there are also different states corresponding to vibrational and rotational motion. The structure is schematically shown in Fig. 3.1. This chapter will mainly be concerned with diatomic molecules.
