摘要: 本文研究了不同取代亚碘酰苯的IO基红外特征吸收峰v as和vs,分别为亚碘酰化合物聚合态结构中 的反对称振动和对称振动。它们与取代基常数σI、σR0、Es间都存在着线性关系。

Abstract: Two characteristic absorption peaks for I-O group of some substituted iodosobcn-zencs were identified in the region 320-625cm-1 by comparing the IR spectra of the substituted iodosobenzenes with corresponding substituted iodobenzen.es. These two peaks could be assigned to asymmetric vibration vas and symmetric vibration vs of group in the polymeric structure of these iodosocompoumds. The cor-relation of vIO to the substituent constants σ1R0 and Es was studied by linear regression analysis. The linear regression equations of the para substituent and meta substituent were obbtained as follows:para: vIO= ρ1σ1RσR0+C meta: vIO= ρ1σ1RσR0+SEs+C
