摘要:Abstract(#br)We apply the algebraic (vibron) model to very long molecular chains, starting from n -alkanes molecules up to polyethylene. The infrared spectrum of CH stretches is computed in an algebraic basis and we obtain analytical formulas for both energy values and inten...

摘要:Abstract(#br)Some simple modifications of the basic vibron model are explored with the aim at making it more useful for practical spectroscopy, in particular for analysis of the spectra of simple molecules with data extending to higher overtones and combination levels. Inclusion ...

摘要:... This analysis allows to establish an exact quantum-mechanical connection between the su(2) vibron model and the traditional description of molecular vibrations. It is shown that the su(2) vibron model corresponds to taking the dominant Δv =±1 interaction in an approxima...

摘要:Abstract(#br)Angular momentum projected mean field theory is used to derive analytic expressions for various matrix elements in the vibron model for diatomic molecules. The results are applied in a search for a realistic description of rotation-vibration spectra in the vibron model...

摘要:Abstract(#br)The vibron model for anharmonic vibrations of simple polyatomic molecules has been modified by explicit inclusion of the bending energy in the vibron hamiltonian, and by incorporating vibrationally and rotationally dependent terms into the main parameters of the model...

摘要:Abstract(#br)A mean field study of triatomic molecules in the vibron model is carried out. Analytical solutions for the mean fields are found, and shape-phase transitions in the model are investigated utilizing these solutions. The Majorana interactions are shown to play an essen...

摘要:Abstract(#br)A U (3)↔ O (4) transitional description of diatomic molecules in the U (4) vibron model is considered. The analysis includes the U (3) and O (4) limits of the theory. Applications to vibrational-like band-heads of several diatomic molecules indicate that there a...

摘要:Abstract(#br)The spectroscopic description of the vibrational excitations of the H 2 16 O molecule is presented in the framework of the su (2) vibron model approximation. Both Darling–Dennison and Fermi-like interactions are taken into account in the energy fit, where an rms...

摘要:... An anharmonic local mode model, the vibron model, is used. It includes all stretch and bend modes as well as Fermi 1:2 resonances between them. All energy levels below 6000 cm −1 are calculated and fit against “experimental” lines. With the help of nine independent pa...

摘要:We report results of the vibrational analysis of monofluoroacetylene (HCCF) within the framework of the vibron model. We test the power (and limitations) of this model against the extensive database that has become available for this molecule. We are able to reach, with 14 par...
