1/N expansion in the vibron model: Diatomic molecules
نویسندگان
چکیده
Using angular-momentum-projected mean-field theory, we develop 1/N expansion solutions for the vibron model of diatomic molecules. Analytic expressions of spectroscopic accuracy are derived for rotationalvibrational energy levels and for the intensities of transitions among them. The results are used in a systematic study of diatomic molecules in the vibron model with a view to finding appropriate Hamiltonians for a realistic description of rotation-vibration spectra. @S1050-2947~98!00905-6#

In order to represent the potential energy function over the whole range of R, many potentialenergy functions have been proposed. In the present paper, we employ many potential energyfunctions, to use Numerov method for solving the nuclear Schrödinger equation for the IFmolecule, as an example of a heteronuclear diatomic molecules.

متن کاملRevisiting the Quantum Group Symmetry of Diatomic Molecules
We propose a q-deformed model of the anharmonic vibrations in diatomic molecules. We analyse the applicability of the model to the phenomenological Dunham’s expansion by comparing with experimental data. Our methodology involves a global consistency analysis of the parameters that determine the q-deformed system, when compared with fitted vibrational parameters to 161 electronic states in diato...

متن کاملAnharmonic Algebraic Model of Thermodynamic Properties of Diatomic Molecules
An algebraic model based on Lie-algebraic techniques is applied to the analysis of thermodynamic vibrational properties of diatomic molecules. The local anharmonic effects are described by a Morse-like potential and corresponding anharmonic bosons associated with the U(2) algebra. A vibrational high temperature partition function and the related thermodynamic functions are derived in terms of t...
متن کاملRegularities in the behavior of dipole moment functions of diatomic molecules at very small internuclear separations
A theoretical approach to calculating the dipole moment function of a diatomic molecule at very small internuclear separations has been suggested. The approach is based on the united-atom model and the LS-coupling approximation. Regularities in the behavior of the dipole moments as functions of the internuclear separation, electronic state, and nuclear charge of the molecule have been found. Wi...
