摘  要:利用原子电性作用矢量(AEIV)对Mannich碱中CO与PO进行结构参数化表征,并通过多元线性回归(MLR)分析,建立了红外光谱振动频率定量结构光谱相关(QSSR)模型,继以留一法(LOO)交互检验(CV)对模型稳定性进行检验。对CO和PO键伸缩振动频率的建模相关系数(Rcum)和交互检验相关系数(RLOO)分别为0.9777,0.9973(CO);0.9433,0.9911(PO)。结果表明,AEIV与Mannich碱中CO与PO伸缩振动频率有很好的相关性。In this paper,atomic electronegativity interaction vector (AEIV) was employed for quantitative structure-spectrum relationship (QSSR) model establishment of infrared spectroscopy vibration frequency of the C=O and P=O bonds in Mannich bases. Then a cross validation (CV) with the leave-one-out (LOO) procedure was performed. The modeling calculated correlation coefficients (Rcum) and Leave-One-Out(LOO) Cross-Validation (CV) correlation coefficients (RLoo) were 0. 9777,and 0. 9973 for C=O;0. 9433,and 0. 9911 for P =O,respectively. It showed that the correlation between AEIV and infrared spectroscopy vibration frequency of C=4 and P=O bonds in Mannich bases was very good.
