Infrared and Raman spectra of acidic (hydrochloric or sulfuric) aqueous solutions of dimethylformamide indicate the existence of a single protonation equilibrium.[Formula: see text]The pK for this reaction was evaluated as −1.35 ± 0.05 from u.v. spectra; a less precise value (−1.1 ± 0.5) was obtained from Raman spectra. This result disagrees with earlier conclusions which favored the existence of two ionization equilibria for dimethylformamide. [Journal translation]

Two compact resonant near-field sensors are introduced for the characterization of aqueous solutions at 5 GHz. They are based on folded substrate-integrate circular half-mode resonators with a planar sensing tip. Owing to the planar design, the sensor is simple and cheap to manufacture, and a sample can be easily coupled to the resonator from the top. The operating principle of the sensor is explained and verified by both simulation and measurement. The radiation of the sensors is quantified by means of a quality factor analysis. Finally, a previously introduced calibration method based on the perturbation theory is applied to the sensors and its accuracy is improved by choosing more suitable reference materials.
