The quadratic linear harmonic oscillator that Schroedinger (1926b) treated is a poor model for a real diatomic molecule
because, in addition to states of infinite number and thus no limit that would correspond to a molecular dissociation into atomic fragments, rotational parameter [B.sub.v] for a particular vibrational state increases appreciably--at least 3 per cent--with each increment of vibrational quantum number v, contrary to the decrease that is found for any real diatomic molecule
; for instance, for HCl the decrease is at least 3 per cent.
In the present work, the Volterra integral equation is used to solve the rovibrational Schrodinger equation of a diatomic molecule
. This method showed that a high order precision is obtained for large order centrifugal distortion constant as [D.sub.v], [H.sub.v], ...

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 .
Two colliding atoms can absorb a photon and be photoassociated into an excited, diatomic molecule
. NIST researchers investigated the fundamental rate at which this process can take place in a Bose-Einstein condensate (BEC) and demonstrated that simple classical saturation arguments do not work when applied to this situation.
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.
Oddly, the second smallest atom also forms the world's largest diatomic molecule
, rivaling biological macromolecules in size, he notes.
Hylleraas potential is used to describe the interaction between two atoms in a diatomic molecule
. We have also investigated the solutions of Hulthen potential and Woods-Saxon potential.
Physicists at LMU and the Max Planck Institute for Quantum Optics (MPQ) achieved to form giant diatomic molecules
and optically detect them afterwards by using a high-resolution objective.
The Franck-Condon overlap integral and the analytical expressions of matrix elements obtained by the use of one-dimensional harmonic oscillators above can be used for diatomic molecules
