Resumo
Os parâmetros estruturais do 1,3,5-trifenilpirazole foram determinados com DFT/cam-B3LYP com o conjunto de bases 6-311++G(d,p). Os resultados da estrutura molecular otimizada são apresentados e comparados com os dados de raios-X disponíveis da molécula ou moléculas muito semelhantes. Uma análise completa dos espectros observados das medições espectrais de FT-IR, RMN (1H e 13C) e absorção UV-Vis com TD-DFT na mesma função e conjunto de bases é fornecida. As propriedades NLO desta molécula também foram investigadas. As distribuições de cargas NPA e MEP estão correlacionadas. Os resultados calculados e os resultados experimentais são discutidos e correlacionados.
