Density-Functional Calculations of Molecular Electron Affinities
نویسندگان
چکیده
Afinidades eletrônicas de doze moléculas pequenas foram calculadas pela teoria de funcional de densidade empregando dois funcionais diferentes(B88-P86 e B3LYP) combinados com três conjuntos de bases diferentes(6-31++G**, 6-311++G** e aug-cc-pVTZ). O método de função de Green para camada na valência exterior também foi empregado para os cálculos de afinidades eletrônicas das moléculas. Duas melhores aproximações foram obtidas com as combinações entre (1)B88-P86 com 6-31++G**, e (2)B3LYP com 6-31++G**. As duas aproximações foram empregadas para cálculos de afinidades eletrônicas de algumas moléculas de tamanho média.
