Frequencies (ν) and integrated intensities A of GeH stretching modes in the IR-spectra of germanes, containing GeCH2Cl and GeCHCl2, have been measured. The doublet character of the ν(GeH) absorption bands has been explained by intramolecular coordination (α-effect) between the chlorine and germanium atoms. The influence of solvents (heptane, carbon tetrachloride, tetrahydrofuran, acetone) on the
测量了包含GeCH 2 Cl和GeCHCl 2的锗烷红外光谱中GeH拉伸模式的频率(ν)和积分强度A。ν(GeH)吸收带的双重特征已经通过氯原子和锗原子之间的分子内配位(α效应)进行了解释。考虑了溶剂(庚烷,四氯化碳,四氢呋喃,丙酮)对ν(GeH)吸收带形状的影响。分析了影响配位的ν(GeH)吸收带强度的因素。分子内协调的焓(δ ^ h)已通过光谱法确定。已经表明,随着与锗原子键合的取代基的受体性质的增加,α效应焓也增加。
