Associative detachment of rubidium hydroxide

Measurement of the associative detachment reaction H − + H → H 2 + e − using a merged - beams method

Optical pumping of Rubidium

A Rubidium high-frequency lamp is used as the pumping light source to excite Rubidium atoms in a sample cell. The pumping source light is filtered to transmit the D1 Rb line and polarizers are used to produce circular polarization. The circular polarization pumping mechanism selectively repopulates the sample cell ground state Rb Zeeman hyperfine levels away from thermal equilibrium populations...

Crystal structure of rubidium methyl­diazo­tate

The title compound, Rb+·H3CN2O-, has been crystallized in liquid ammonia as a reaction product of the reductive ammonolysis of the natural compound streptozocin. Elemental rubidium was used as reduction agent as it is soluble in liquid ammonia, forming a blue solution. Reductive bond cleavage in biogenic materials under kinetically controlled conditions offers a new approach to gain access to s...

Rubidium(I) monensinate dihydrate

In the title complex, [Rb(C(36)H(61)O(11))]·2H(2)O, the Rb(+) cation is coordinated by seven O atoms of monensin. Rb-O distances range from 2.7870 (17) to 3.1429 (17) Å. Both O atoms of the carboxyl-ate group are involved in the coordination of Rb. The structure displays inter- and intra-molecular O-H⋯O and C-H⋯O hydrogen-bonding inter-actions.

Determination of Rubidium in Seawater

Rubidium concentrations in seawater from various locations and depths to 3,900 m have been determined using two independent techniques--direct flame photometry and mass spectrometry. Results of these two techniques agree within estimated errors and indicate that the rubidium content in the oceans is uniform within H$% with values varying about 120 pg/liter. Sediment from the sea floor below a d...
