Modelos para dispersão Raman em polímeros conjugados
Raman dispersion refers to the dependence of the position of Raman bands on the energy of the exciting radiation. In this work, the three main models currently used to explain this phenomenon (Conjugated Length Model, Amplitude Mode Model and Effective Conjugation Coordinate Model) are discussed. Raman dispersion is a consequence of pi electron delocalization, but each model describes in a different way how pi electron delocalization affects the position of Raman bands. Here the features, qualities and problems of the three models are highlighted.
