Theory methods (BLYP, B3PW91, and B3LYP) with the 6-311G (d,p) basis set were used to calculate the molecular structure, vibrational frequencies and infrared intensities of the title compound. A comparison between the calculated geometric parameters and the corresponding single-crystal X-ray structure data of the title compound was performed. It was observed that the harmonic vibrations, calculated for this
摘要 使用 6-311G (d,p) 基组的密度泛函理论方法(BLYP、B3PW91 和 B3LYP)计算标题化合物的分子结构、振动频率和红外强度。将计算的几何参数与标题化合物的相应单晶 X 射线结构数据进行比较。据观察,通过 B3LYP/6-311G (d,p) 方法计算的该化合物的谐波振动与实验 IR 和拉曼光谱数据 (RMSmol = 9.63) 非常一致。此外,标题化合物的理论振动光谱通过 PED 评估,使用 SQM 2.0 程序。在所研究的方法中,借助 PAVF 1.0 程序计算出 B3LYP 的总体性能更好。
