【摘要】 <正> 由于温度的大幅度变化,分子的某些吸收带的强度将会产生明显的改变,但关于分子的红外吸收光谱与温度关系的研究尚少.在有机锂络合物的红外光谱研究中,我们发现邻甲氧基苯酚锂络合物显示了与其他锂络合物明显不同的特性,在改变温度过程中,这种不同结构效应的特性更加明显.为此我们从+100～-130℃的较宽温度变化区域内,测定了它的变温红外光谱.在低于室温时,随着温度急剧下降,其中某些吸收带强度更多还原

【Abstract】 In previous papers we reported that the lithium complex of o-methoxyphenol showed quite different characteristics in their IR spectra as compared with the spectra of other organic lithium complexes, and assumed that the change of their spectra with temperature implied the change of structure at different temperatures.In this paper we measured the IR spectra of the isotopic lithium complex of o-methoxyphenolate in a rather wide temperature range（-130℃～100℃） and found that some characteristic IR spectra bands(970, 790, 500, 460, 410cm^-1) of the lithium o-methoxyphenolate were enhanced with lowering temperature, the two bands(970, 790cm^-1) are assumed to belong to the stretching frequency of the network structural form of superoxide.更多还原
