Intermolecular Interactions in 3-Aminopropyltrimethoxysilane, N-Methyl-3-aminopropyltrimethoxysilane and 3-Aminopropyltriethoxysilane: Insights from Computational Abstract In this work, a computational spectroscopy approach was used to provide a complete assignment of the inelastic neutron scattering spectra of three title alkoxysilane derivatives—3-aminopropyltrimethoxysilane (APTS), N-methyl-3-aminopropyltrimethoxysilane (MAPTS), and 3-aminopropyltriethoxysilane (APTES). The simulated spectra obtained from density functional theory (DFT) calculations exhibit a remarkable…

Astroquímica: A Identificação de Moléculas pela Luz das Estrelas. Abstract Astrochemistry is the science that studies atoms, molecules and chemical reactions in outer space. Through Astrochemistry we now know that space is full of molecules and that many molecules on planet Earth were formed in outer space. Let’s discuss where and how molecules are formed…
