This is the case in solids with small values of dielectric constant, such as insulators. Frenkel excitons are localized excitations, that is, localized on the same atom or molecule, with a binding energy on the order of – eV. Frenkel excitons are usually found in alkali halides and organic molecular crystals composed of aromatic molecules.

However, the small size of these pigment aggregates in the pigment-protein complexes as well as the role of the protein, which is responsible for the structural arrangement of the complex, clearly will have a dramatic. Excitons are considered as the basic concept used by describing the spectral properties of photosynthetic pigment-protein complexes and excitation dynamics in photosynthetic light-harvesting antenna and reaction centers.

Excitons, Magnons and Phonons in Molecular dings of a symposium, Beirut, A. Zahlan, dge University Press, New York, xii + Author: D. Chesnut. The theory of excitons in molecular crystals (see, for example, [1, 2]) is usually restricted to the lowest (dipole—dipole) interaction between molecules.

However, considerable advances in the experimental techniques have set problems which cannot be solved without extension of the theory to higher multipole : Yu. Khokhlov. Part of the Physics of Solids and Liquids book series (PSLI) Abstract In crystals of insulators and semiconductors, when an incident photon is absorbed exciting an electron from the valence to the conduction band, a positive charged vacancy, called a hole, is created in the valence by: 1.

Organized into 15 chapters, this book begins with an overview of the several processes concerning triplet excitons leading to magnetic-field sensitive luminescence in organic crystals and related compounds. This text then examines the methods of investigation of the exciton band structures in molecular crystals.

Excitons in organic molecular crystals Conference Paper in Optical Materials 28(s 1–2) vol.2 August with 17 Reads How we measure 'reads'. the exciton dispersion in molecular crystals arises from the interplay between hopping and the exchange e-h interaction.

The ab initio BSE results confirm these conclusions. Excitons. Excitons refer to electronic excited states that are not localized to a particular molecule. But beyond that there are many flavors. We will concentrate on Frenkel excitons, which refer to excited states in which the excited electron and the corresponding hole (or electron vacancy) reside on the same molecules remain electrically neutral in the ground and.

96B Abstract The results of some theoretical and experimental studies which have appeared in the literature concerning the behavior of molecular crystals with high concentration of excitons are reviewed. General properties. In molecular crystals the energetic separation between the top of the valence band and the bottom conduction band, i.e.

the band gap, is typically –4 eV, while in inorganic semiconductors the band gaps are typically 1–2 eV. This implies that they are, in fact, insulators rather than semiconductors in the conventional sense. The effect of the head-tail orientational disorder, of Ising type, on the vibrational exciton line shapes in molecular crystals is investigated.

The eigenstates of orientationally disordered crystals are calculated and analyzed by means of lattice dynamics calculations with dipolar intermolecular interactions. A numerical simulation, configurationally averaged, of the two randomly Cited by: 1.

The interaction of Frankel excitons with optical phonons in molecular crystals is studied by means of a Green's function method in which the use of a canonical transformation allows most of the exciton–phonon interaction to be treated nonperturbatively.

The self‐energy of the Green's function is then expanded in terms of the intermolecular by: Title: The Solid State.

Clearly, a better approximation must include the effect of excitation wavesI2 with R~O (charge-transfer excitons, or ion-pair excitons). The mixing of ion-pair excitons with neutral exciton states has been previously considered,1a,14 However, there has been no systematic discussion of the configuration.
