Espectroscopia Vibracional Abstract “Vibrational spectroscopy” is the technique that measures the interaction of electromagnetic radiation with the vibrational movements of a molecular system. Any system that contains atoms linked together has vibrational movements, from diatomic molecules to biological systems and the most diverse materials. Therefore, the various vibrational spectroscopy techniques are widely used both in…

Inside PEF: Chain Conformation and Dynamics in Crystalline and Amorphous Domains Abstract A thorough vibrational spectroscopy and molecular modeling study on poly(ethylene 2,5-furandicarboxylate) (PEF) explores its conformational preferences, in the amorphous and crystalline regions, while clarifying structure property correlations. Despite the increasing relevance of PEF as a sustainable polymer, some of its unique characteristics are…

Hydrogen Bond Dynamics of Cellulose through Inelastic Neutron Scattering Spectroscopy Abstract This work explores the dynamics of hydrogen bond networks in cellulose through inelastic neutron scattering (INS) and periodic CASTEP calculations. Estimated spectra were based on the crystal structure of cellulose I alpha and I beta and replicate the INS spectrum of cellulose samples with…
