Abstract The microwave spectrum of HCCF and DCCF has been investigated in all vibrational states with energy up to 1500 cm -1 . In the ground state and low-lying vibrational states mm-wave measurements up to 210 GHz were made. In some cases a detailed analysis of the vibrational state rotation spectrum including the effects of l-type resonance, and the determination of the anharmonicity constant gtt was possible. The rotational spectra of combination states of the type (vt = 2, vt′ = 1) were observed and partially analyzed, which is, to our knowledge, the first time this has been accomplished. The low-lying vibrational states of 13 C species of HCCF and DCCF were also observed. The 9.4 μm P(14) CO2-laser line was observed to produce a reduction in intensity in the ground state and an increase in intensity in the v3 = 1 excited state J = 0 → 1, 1 → 2, 2 3 transitions of DCCF.

Gold porous membrane electrode has been used for the potentiometric determination of small amounts of sulfur dioxide absorbed in the solutions of sodium tetrachloromercurate or sodium hydroxide. Sulfur dioxide is released by the reaction with an acid into a stream of nitrogen and led to the electrode immersed into the solution of iodine monochloride. Part of SO2 penetrates through the membrane pores into the solution where it is oxidized. The electrode redox potential change is a measure of the SO2 concentration in the absorption solution. In the solution of 1 . 10-5 M[ICl2]- in 0.02 M-HClO4 the limit of quantitation was found to be 0.07 ng SO2 . ml-1. The relative standard deviations of 1.4% and 2.5% were found for the determinations of 10 ng and 0.5 ng of SO2, respectively. Higher concentrations of H2S interfere only in the hydroxide solution. About 10 samples can be analyzed per one hour.
