Modelagem computacional de Hidrocarbonetos Aromáticos Policíclicos em Nebulosas Planetárias

Revista Mundi Engenharia, Tecnologia e Gestão (ISSN: 2525-4782), 2023
Nebulosas Planetárias são objetos extremamente importantes por enriquecerem o meio interestelar com diversos elementos produzidos por sua nucleossíntese, e contribuírem com a evolução química das galáxias. Com isso, temos a formação de moléculas de Hidrocarbonetos Aromáticos Policíclicos (PAHs), que são as moléculas orgânicas mais abundantes no espaço ...

Predicting Ti-49 NMR Chemical Shift With New NMR-DKH Basis Set. [PDF]

J Comput Chem
A new NMR‐DKH basis set was proposed for Ti atom and the δ49Ti was studied in a set of 41 + 9 (calibration‐blue/validation‐red) Ti(IV) complexes, resulting in a mean absolute deviation of only 50 ppm with the GIAO‐OLYP/NMR‐DKH/IEF‐PCM(UFF)//BLYP/def2‐SVP/IEF‐PCM(UFF) protocol.
