The interaction of oxatomide (OXA), azacyclonol (AZA) and chloropheniramine (ClPA) antihistamine drugs with iodine was studied spectrophotometrically in different solvents and at three different temperatures. The electronic, FT-IR, far-IR, and mass spectra of the resulting charge-transfer (CT) complexes were recorded, in addition to thermal analysis ...

Complex effective relative permittivity of soil samples from the taunus region (Germany)
Journal of Earth Science, 2010The most important parameter affecting ground-penetrating radar (GPR) measurements is the complex effective relative permittivity ɛr,eff* because it controls the propagation velocity and the reflection of GPR pulses. Knowing ɛr,eff* of soils passed through by electromagnetic waves increases accuracy in soil thickness and interface identification ...

Abstract In this paper, the expression of relative complex permittivity is deduced based on considering the effect of charged particle’s (electrons and ions) flow velocity. The theoretical deduction manifests that the relative complex permittivity is related to temperature, pressure and frequency, especially the flow velocity of charged particles. In

Several techniques for measuring accurately the complex permittivity of ceramics using a Fabry-Perot resonator have been developed in millimeter frequency range. Accurate measurement became possible at 40-60 GHz by the three new techniques: 1. exact centering of the sample; 2. exact determination of the sample normal direction parallel to the resonator
