本文研究了取代苯甲酸的羰基和羟基伸缩振动频率与苯环上取代基的Hammett常数σ值之间的线性关系;双(η~5-环戊二烯基)-双(取代苯甲酸)钼(Ⅳ)配合物[Cp_2Mo(O_2CC_6H_4X)_2](Cp=环戊二烯基;X=m-或p-NO_2、F、Cl、Bf、I、CH3、OCH_3、H)的羰基伸缩振动频率与取代基的σ值之间的线性关系,及Cp_2Mo(O_2CC_6H_4X)_2中苯甲酸根的配位方式。本文还提供了一个利用分辨率较低的仪器,比较精确地读出峰位的简便方法。
In this paper, the linear relationship between the vibrational frequencies of carbonyl and hydroxyl groups of substituted benzoic acids and the Hammett constant σ values of the substituents on benzene rings was investigated. The molar ratio of bis (η 5 -cyclopentadienyl) -bis (substituted benzoate) molybdenum The carbonyl stretching vibrational frequency of the complex [Cp_2Mo (O_2CC_6H_4X) _2] (Cp = cyclopentadienyl; X = m- or p-NO_2, F, Cl, Bf, I, CH 3, OCH 3, H) The linear relationship between the σ values of the substituents and the coordination pattern of benzoate in Cp_2Mo (O_2CC_6H_4X) _2. This article also provides an easy way to read peak positions more accurately with less-resolution instruments.
