HQ(4) AND SUQ(2) QUANTUM GROUP SYMMETRIES IN Diatomic-Molecules
Physical review. A Atomic molecular and optical physics, 1991Co-Authors: Zhe Chang, Hong YanAbstract:We develop a model with ${\mathit{H}}_{\mathit{q}}$(4) and ${\mathrm{SU}}_{\mathit{q}}$(2) quantum group symmetries to describe the vibrational and rotational spectra of Diatomic Molecules. The representations of ${\mathit{H}}_{\mathit{q}}$(4) and ${\mathrm{SU}}_{\mathit{q}}$(2) and solutions to the quantum systems of q oscillators and q rotators are provided. We emphasize that the energy spectra of the q oscillator and q rotator exhibit remarkably the properties of the infrared, vibrational, and rotational Raman spectra as well as vibrational and rotational structures of electronic transitions of the Diatomic molecule. When the parameters are properly selected, the spectra of this model coincide with the observed spectra of Diatomic Molecules. It is suggested that ${\mathit{H}}_{\mathit{q}}$(4) \ensuremath{\bigotimes}${\mathrm{SU}}_{\mathit{q}}$(2) is an essential symmetry of vibrations and rotations in Diatomic Molecules.

The SUq(2) quantum group symmetry and Diatomic Molecules
Physics Letters A, 1991Co-Authors: Zhe Chang, Hong YanAbstract:Abstract We set up the q -rotator model with SU q (2) quantum group symmetry for a description of infrared emission and absorption, rotational Raman spectra and rotational structure of electronic transitions and vibrations of Diatomic Molecules. When the parameters of the model are well selected, the spectra of the SU q (2) quantum group model coincide with the observed spectra of Diatomic Molecules to satisfactory accuracies.

Q-DEFORMED VIBRON MODEL FOR Diatomic Molecules
Physical review. A Atomic molecular and optical physics, 1994Co-Authors: R. N. Alvarez, Dennis Bonatsos, Yu. F. SmirnovAbstract:A deformed version of the vibron model for Diatomic Molecules is constructed. Both the O(4) and U(3) dynamical symmetries of the model are rewritten, using the concept of complementary subalgebras, in a more convenient form, which is subsequently deformed. The present model unifies the so far independent successful quantum-algebraic approaches to rotational and to vibrational spectra of Diatomic Molecules. In addition, the method can be used for the construction of deformed versions of the U(5) and O(6) limits of the interacting boson model of nuclear structure.

the rotation vibration spectrum of Diatomic Molecules with the tietz hua rotating oscillator
arXiv: Quantum Physics, 2012Co-Authors: M Hamzavi, A A Rajabi, Karlerik ThylweAbstract:The Tietz-Hua (TH) potential is one of the very best analytical model potentials for the vibrational energy of Diatomic Molecules. By using the Nikiforov-Uvarov (NU) method, we have obtained the exact analytical s-wave solutions of the radial Schr\"odinger equation (SE) for the TH potential. The energy eigenvalues and the corresponding eigenfunctions are calculated in closed forms. Some numerical results for Diatomic Molecules are also presented.
