Molecular Structures of Perfluoromethyl Iodide, Perfluoroethyl Iodide, and Perfluoroisopropyl Iodide

The Journal of Chemical Physics, 1972
The molecular structures of three fully halogenated alkanes have been investigated by electron diffraction. The following rg parameters were determined for CF3I: C–I=2.101±0.009 Å; C–F=1.344±0.004 Å; and ∠FCI=111.3°±0.4°. For CF3CF2I: C–I=2.142±0.023 Å; C–F=1.338±0.004 Å; C–C=1.523±0.027 Å; with ∠CCI=113.4°±0.8°; ∠CCF=109.9°±0.8°; and ∠ICF=109.4°±1.0°.

EXCHANGE REACTIONS OF IODIDE ION WITH AROMATIC IODIDES

Canadian Journal of Chemistry, 1951
The exchange reactions of iodide ion with o- and p-nitroiodobenzene in the temperature range about 170°–238°C were apparently second order with activation energies of approximately 29 and 33.5 kcal. per mole respectively. In the same temperature range the exchange of iodide ion with iodobenzene and m-nitroiodobenzene appeared to be first order ...

EXCHANGE REACTIONS OF ALICYCLIC IODIDES WITH SODIUM IODIDE

Canadian Journal of Chemistry, 1951
The activation energies for the exchange reactions between sodium iodide and cyclopentyl, cycloheptyl, cycloöctyl, cyclopentadecyl, and 2-heptyl iodides were all in the range 21 ± 1 kcal. per mole. For cyclohexyl iodide the value was 25.6 kcal. per mole.

Double Salts Iodide Scintillators: Cesium Barium Iodide, Cesium Calcium Iodide, and Barium Bromine Iodide

Crystal Research and Technology, 2013
AbstractIn this study we review the state‐of‐the‐art for double salt iodide scintillators, in particular cesium barium iodide (CBI), cesium calcium iodide (CCI) and barium bromine iodide (BBI), as well as report on their scintillation and optical properties.

Iodide goiter and the pharmacologic effects of excess iodide

The American Journal of Medicine, 1969
Abstract Chronic ingestion of iodide or iodide-generating organic compounds in amounts of ten or more times the daily requirements for hormone biosynthesis leads to iodide goiter in certain subjects. Predisposing factors are uncertain but may involve a damaged thyroid parenchyma; this must, however, be minimal since full recovery of normal thyroid ...

The Relative Rates of the Reactions of Hydrogen Iodide and Deuterium Iodide with Methyl Iodide

The Journal of Chemical Physics, 1950
The relative rates of the reactions of hydrogen iodide and deuterium iodide with methyl iodide were studied by a competitive method at 310° and 250°C. The analysis of hydrogen-deuterium mixtures was accomplished by means of a simple viscometer with an accuracy of 0.5 percent. It was found that hydrogen iodide reacts about 1.4 times as fast as deuterium
