摘要

提出了一种计算微波频率下1% ~ 40%浓度范围内溶质偶极矩的新方法。应用该方法分析了氯醛(CCl3-CHO)在苯溶液中的介电数据。用含浓度线性项和二次项的方程拟合了介电常数与浓度的关系。该方法得到的氯醛偶极矩为7.07×10-3 SI单位，比古根海姆静力法计算的偶极矩高36%。

A new expression for the calculation of the solute dipole moment in the concentration range 1 % – 40 % at microwave frequencies

A new method for the calculation of the solute dipole moment in the concentration range 1 % - 40 % at microwave frequencies is proposed. It is applied for the analysis of the dielectric data of chloral (CCl3-CHO) in solution in benzene at 9.8 GHz. The concentration dependence of the permittivity is fitted by the equation including linear and quadratic terms of the concentration. The dipole moment of chloral obtained by this method is 7.07×10-3 SI units, a value 36 % higher than the one computed by the Guggenheim static method.
