Journal ArticleDOI
Raman spectroscopy of polyconjugated molecules and materials: confinement effect in one and two dimensions
TL;DR: Theoretical computations and specific Raman experiments demonstrate that a molecular approach provides a unified key to the interpretation of the Raman response both of linear polyconjugated polymers (polyacetylene) and of nanostructured graphitic materials.
Journal ArticleDOI
A simple interpretation of the vibrational spectra of undoped, doped and photoexcited polyacetylene: Amplitude mode theory in the GF formalism
TL;DR: In this article, the Amplitude Mode Theory worked out for obtaining a unified interpretation of the vibrational spectra of Polyacetylene can be reformulated in a simpler and more complete way in terms of straightforward concepts of moleculare dynamics.
Journal ArticleDOI
Common force field for graphite and polycyclic aromatic hydrocarbons
TL;DR: In this paper, a valence force field based on Huckel's theory has been developed, which allows to establish a close correlation between phonons of graphite and the normal modes of small polycyclic aromatic hydrocarbons (such as coronene and hexabenzocoronene).
Journal ArticleDOI
Confinement potential and pi -electron delocalization in polyconjugated organic materials.
TL;DR: Frequency dispersions with chain length have been experimentally determined from Raman-scattering data published previously on a series of oligomers and polymers of paraphenylene, paraphenhene vinylene, thiophene, N-protected pyrrole, pyr role, and furan.
Journal ArticleDOI
Origin of the D line in the Raman spectrum of graphite: A study based on Raman frequencies and intensities of polycyclic aromatic hydrocarbon molecules
TL;DR: In this article, a common valence force field for polycyclic aromatic hydrocarbons (PAHs) and graphite has been used in order to explain their Raman spectra from a unified viewpoint.
