We take an atomic nucleus of electric charge +Z > 0 as being located at a centre of coordinates with [xi] = 1 and [eta] = -1; the other focus at distance d has coordinates [xi] = 1 and [eta] = 1 and is a dummy centre with Z = 0, which might, however, become the location of another atomic nucleus in the case of a diatomic molecule, such as [H2.
Unlike the odourless and colourless diatomic molecule oxygen we breathe, ozone is a tri-atomic molecule that bonded in one.
The factor of five in the numerator of Equation 1 is the number of kinetic degrees of freedom for a diatomic molecule at room temperature; in addition to the three translational degrees of freedom, diatomic molecules also have two rotational degrees of freedom.
In the classical regime the sum of probability densities |ps1|2+|ps2|2 of the detached-electron from individual atoms is equal to the probability density |ps|2from the diatomic molecule.
So two atoms of the mystery element frequently bond together to form a more stable diatomic molecule (particle containing two atoms).
The word "excimer" is a contraction of "excited dimer," a dimer being a diatomic molecule of an inert gas whose halogen atoms are bound in the highly charged (excited) state, temporary and unstably.
Here we consider the Morse interaction [2,12] which represents an approximation to vibrational motion of a diatomic molecule.
In ellipsoidal coordinates, one focus of an ellipsoid is located at or near the atomic nucleus; the other focus, at distance d, is merely a dummy location; as the latter can become the location of a second atomic nucleus, the associated amplitude functions become formally applicable to a diatomic molecule, which has been the reason for the attention given to these coordinates [9].
Weidemuller's group created molecules made of an atom of lithium and one of cesium, similar to Ye's diatomic molecule of potassium and rubidium.
Two colliding atoms can absorb a photon and be photo-associated into an excited, diatomic molecule.
Above the dissociation limit of a diatomic molecule, the effective radius of each separate atomic fragment decreases with increasing temperature, but, for two interacting strongly bound diatomic molecules within a weakly bound tetratomic molecule, the effective radius of each fragment again increases with increasing temperature.
