4-取代酰基PMP紫外光谱和氢键强度的研究

Study of UV Spectrum and Hydrogen bond Strength of Substituting Acyl-PMP

研究了新试剂４－对甲氧苯甲酰基ＰＭＰ、４－邻甲氧苯甲酰基ＰＭＰ与４－（α－呋喃甲酰基）－１－苯基－３－甲基－吡唑啉－５－酮在不同极性溶剂中的紫外吸收光谱．通过Ｒ吸收带的变化，首次分别计算出了它们在相应溶剂中的氢键强度。

The UV spectrum of 4-p-Methoxy benzoyl-PMP 4-o-Methoxy Benzoyl-PMP and 4-α-Furoyl-PMP in Different Polar Solvent were studied. The Hydrogen bond strength in Corresponding solvent were calculated for the first time from the change of R absorption band.The correlation between hydrogen bond strength and the molecula structure was discussed.
