electronic spectral line shape of a diatomic molecule

Electronic Spectral Line Shape of a Diatomic Molecule

The electronic absorption spectral line shape of a diatomic molecule with harmonic potential curves is calculated using the time correlation function formalism. Both the equilibrium shift and the frequency shift of the two linking electronic states ate taken into account. The spectrum is also calculated using the cumulated expansion which is related to the correlation function of the time-d...

The Spectral Line Shape of Exotic Nuclei

The quadrupole strength function of 28O is calculated making use of the SIII interaction, within the framework of continuum-RPA and taking into account collisions among the nucleons (doorway coupling). The centroid of the giant resonance is predicted at ≈ 14 MeV, that is much below the energy expected for both isoscalar and isovector quadrupole resonances in nuclei along the stability valley. A...

Diatomic molecule as a quantum entanglement switch

We investigate a pair entanglement of electrons in diatomic molecule, modeled as a correlated double quantum dot attached to the leads. The low-temperature properties are derived from the ground state obtained by utilizing the Rejec-Ramšak variational technique within the framework of EDABI method, which combines exact diagonalization with ab initio calculations. The results show, that single-p...

Spectral simulations of polar diatomic molecules immersed in He clusters: application to the ICl (X) molecule

A recently developed quantum-chemistry-like methodology to study molecules solvated in atomic clusters is applied to the ICl (iodine chloride) polar diatomic molecule immersed in clusters of He atoms. The atoms of the solvent clusters are treated as the ‘electrons’ and the solvated molecule as a structured ‘nucleus’ of the combined solvent-solute system. The helium–helium and helium-dopant inte...

Establishment a CHO Cell Line Expressing Human CD52 Molecule

Background: CD52 is a small glycoprotein with a GPI anchor at its C-terminus. CD52 is expressed by Normal and malignant T and B lymphocytes and monocytes. There are detectable amounts of soluble CD52 in plasma of patients with CLL and could be used as a tumor marker. Although the biological function of CD52 is unknown but it seems that CD52 may be involved in migration and activation of T-cells...
