| 摘 要： | 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。

Studies on IR Frequencies of Carbonyl and Hydroxyl Groups of Substituted Benzoic Acids and Bis-(η~5-Cyclopentadienyl) Molybdenum (Ⅳ) Benzoate Complexes |
| |
| Abstract: | In this paper,the linear relationship of Hammett's constant σ,and the stretching frequencies of carbonyl and hydroxyi groups of substituted benzoic acids and their molybdenum (Ⅳ) complexes Cp2Mo (O2CC6H4X)2] ( Cp =η5- cyclopentadienyl; X == m- or p- NO2, F, Cl, Br, I, CH3, CH3O, H , groups ) were studied. The coordination manner of benzoate group in these complexes was studied as well,A method which can accuratly read the wave number using a lower resolution apparatus was proposed. |
