Abstract

The relationship between the dielectric and radio brightness characteristics of aqueous solutions of (NH₄)₂[PdCl₄] at low concentrations at 298.15 K were considered. The dielectric relaxation parameters representing the disturbance of the H-bond network in the transition from water to solution were calculated from experimental data on the complex permittivity near the maximum of dispersion of water and solutions. These data and the Fresnel equations were used to find the quasi-optical coefficients and radio brightness characteristics of aqueous solutions in the centimeter and millimeter bands. The radio brightness characteristics of model solutions were determined with a high-sensitivity radiometer at a frequency of 61.2 GHz. The radio brightness temperature in the model solutions decreases in the transition from water to solution according to both experimental and calculated data. It was shown that the intrinsic radiation of the solution reflects the contributions of both dipole and ionic losses, which still remain significant in the millimeter band. They may even determine the difference in the signs of the changes in the radio brightness. Basics of a new approach to studying solutions containing complex ions based on their intrinsic radiation in the millimeter band were developed.

摘要

（NH ₄）₂ [PdCl ₄ ]水溶液的介电常数和射电亮度特性之间的关系认为在298.15 K下的低浓度。从关于水和溶液的最大分散附近的复介电常数的实验数据，计算出代表氢键网络在从水到溶液的过渡过程中的扰动的介电弛豫参数。这些数据和菲涅耳方程用于查找厘米和毫米带中水溶液的准光学系数和射电亮度特性。使用高灵敏度辐射计在61.2 GHz的频率下确定模型解决方案的无线电亮度特性。根据实验数据和计算数据，模型溶液中的无线电亮度温度在从水到溶液的转变过程中降低。结果表明，溶液的本征辐射反映了偶极损耗和离子损耗，这在毫米带中仍然很明显。他们甚至可以确定无线电亮度变化的符号差异。开发了一种新方法的基础，该方法用于基于毫米带中的固有离子来研究包含复杂离子的溶液。
