Gaussian b3lyp

WebMar 15, 2013 · For geometry optimization, the density functional theory method B3LYP was used in the Gaussian 03 program [12]. For all calculations, we used the 6-311G (d, p) basis set for all atoms. All calculations have been optimized from several initial geometries, being the complex with C1 symmetry more stable. After this procedure, the vibrational ... Webcalculations were performed with the GAUSSIAN 09 suite of programs. Results and Discussion Geometries angle (deg) Figure 1 shows the B3LYP/6-31G (d, P) optimized structures under study. It can be seen from this figure, carboxy benzene as a donor and thiophene iso- indene as an acceptor are connected by (CH) 2 as a bridge.
