A simple two-particle model of excitons in conjugated polymers is proposed as an alternative to usual highly computationally demanding quantum chemical methods. In the two-particle model, the exciton is described as an electron-hole pair interacting via Coulomb forces and confined to the polymer back...
In quantum mechanics, the particle in a box model (also known as the infinite potential well or the infinite square well) describes a particle, which is free to move in a space surrounded by impenetrable barriers. In classical systems, for example a ball trapped inside a heavy box, the ...
In quantum mechanics, the particle in a box model (also known as the infinite potential well or the infinite square well) describes a particle free to move in a small space surrounded by impenetrable barriers. The model is mainly used as a hypothetical example to illustrate the differences ...
Uses the particle-in-the-box model to describe the confinement of matter due to its quantum mechanical nature on the microscopic as well as macroscopic level. The wave-particle dualism is also discussed. Confinement of particles; The eigenstates and wave functions of the PIB model; Wave-particle...
In the past 20 years, scientists have learned how tomake systems in which electrons behave as if they are trapped in a box.Unexpectedly, this toy model, meant to be a teaching tool, is being used inimportant applications: the lasers used at supermarket counters and in yourCD player are ...
Within the molecular orbital model, all the electrons in the molecule occupythe lowest-energy molecular orbitals. (This is analogous to an atom’s electronic ground state, in which allelectrons in the atom occupy the lowest energy atomic orbitals.) When a photon is absorbed of the proper...

The recently proposed particle-in-a-box model of one-dimensional excitons in conjugated polymers is applied in calculations of optical absorption and electroabsorption spectra. It is demonstrated that for polymers of long conjugation length a superposition of single exciton resonances produces a line shap...
