This chapter evaluates diatomic molecules. Atomic orbitals of the correct symmetry on adjoining atoms interact to form a bonding combination orbital and an antibonding combination orbital. Molecular orbitals that display cylindrical symmetry when viewed along the bond axis are called σ orbitals.

Abstract Double ionisation of most of the experimentally accessible diatomic molecules has been studied previously by several techniques, including Auger spectroscopy, double electron transfer, kinetic energy release, and high-level theory. New double photoionisation spectra of HBr, HI, N2, CO, NO, O2, Br2, ICl, and I2 are presented here

Photoabsorption of diatomic molecules
Czechoslovak Journal of Physics, 2006Radiative transport of energy plays an important role in many plasma processing devices. Jets of thermal plasma are produced in plasma generators with electric arcs. The experimental observation of radiation transfer is very difficult due to experimental conditions. In such cases, the mathematical modeling is of great importance.

Abstract In this section we shall review some of the mathematical ideas you should have been exposed to in a course on quantum mechanics. If you find that you still do not understand the material described in this section and would like to read more, I suggest you try Chapter 8 of Feynman et al. (1966).

Modelling of diatomic molecules
Molecular Physics, 2016ABSTRACTA new general molecular potential is introduced to model diatomic molecular structures. Eigenfunctions and rotational-vibrational energy eigenvalue equation of the Schrodinger particle in the presence of centrifugal term are obtained for the general molecular potential.

Electronic States in Diatomic Molecules
2007In this Chapter we specialize the concepts given in Chapter 7 for the electronic states by introducing specific forms for the wavefunctions in diatomic molecules. Two main lines of description can be envisaged. In the approach known as molecular orbital (MO) the molecule is built up in a way similar to the aufbau method in atoms, namely by ideally ...

The periodicity of diatomic molecules
Journal of Molecular Structure: THEOCHEM, 1982Abstract The possibility of molecular periodicity is discussed. A periodic table of diatomic molecules classified according to their electronic configuration is compiled. Many important properties including the dissociation energy, force constant, internuclear distance, electronic term symbols, transition frequency between states A and X ...

In a diatomic molecule, the interaction between the atoms depends on their electronic configuration. It is conceivable that a molecule is stable if one of the atoms is electronically excited, and unstable if both atoms are in their ground state. We study here such a scheme, and we focus in particular on the dissociation of the molecule when the ...
