diatomic molecule, [alpha] changes during the course of the vibration

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 [9].

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.
