Abstract:
A simplified theoretical approach for modeling the off-resonance Raman scattering of molecular models of confined graphene (polycyclic aromatic hydrocarbons, PAHs) is presented and compared with the results from density functional theory calculations. This theoretical analysis not only allows for a quick estimate of the Raman scattering activity, but also correlates the Raman response to simple quantities directly linked to the molecular electronic structure. Owing to its simplicity and computational convenience the model can be applied to extended graphitic systems. The results of the Hückel calculations of the off-resonance Raman bond polarizability parameters of nanometer sized armchair and zizgag graphene flakes are shown.

01:26Raman Spectroscopy Instrumentation: Overview
The monochromatic laser source, typically using visible or near-infrared radiation, generates a highly focused beam of light. This light interacts with the molecules of the sample, scattering some of the light. Liquid and gaseous samples are usually tested in ordinary glass capillaries, while solids can be analyzed as powders packed in capillaries or as potassium...
