对包括缔合和非缔合液体在内的许多双组分体系进行了介电弛豫测量。发现含有两个烷基卤化物的混合物只有一个分散体。含有卤代烷和醇的混合物显示出两个分散区域，单独的复杂平面轨迹在形式上类似于为单独组分找到的分散体。在几种烷基卤化物-烃混合物中的弥散轨迹与纯卤化物中没有显着差异，尽管在低频下观察到了原因不明的微小偏差。在所研究的正丙醇-2-甲基戊烷混合物中，醇的多重分散的相对幅度在33%正丙醇浓度下几乎不受影响，但在14%正丙醇浓度下变化很大。根据夏拉马赫关于这些混合物的分子性质的建议，讨论了结果。
Dielectric relaxation measurements were made on a number of two‐component systems involving both associated and nonassociated liquids. A single dispersion was found for a mixture containing two alkyl halides. A mixture containing an alkyl halide and an alcohol showed two dispersion regions, the separate complex plane loci being similar in form to the dispersions found for the separate components. The locus of the dispersion in several alkyl halide‐hydrocarbon mixtures was not significantly different from that in the pure halides although small deviations of unknown origin were observed at low frequencies. In the 1‐propanol‐2‐methylpentane mixtures studied, the relative amplitudes of the multiple dispersions, characteristic of the alcohol, were little affected down to a concentration of 33 mole percent 1‐propanol but had changed drastically at a concentration of 14 mole percent 1‐propanol.The results are discussed in terms of Schallamach's suggestions concerning the molecular nature of these mixtures and t...
