Rubidium metaborate, Rb3B3O6.

Rubidium metaborate, Rb3B3O6, was obtained by the reaction of Rb2CO3 and BN using a radiofrequency furnace at a maximum reaction temperature of 1173 K. The crystal structure has been determined by single-crystal X-ray diffraction. The space group is R3c, with all atoms positioned on a twofold axis (Wyckoff site 18e). The ionic compound is isotypic with Na3B3O6, K3B3O6 and Cs3B3O6.

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.

Candlestick rubidium beam source

Many atomic physics laboratories rely on beams of alkali atoms for their experiments, for example in the atom optics and laser cooling communities. Rubidium is commonly used, due to the fortunate coincidence of the dipole resonant transition with the optimum output wavelength of low-cost AlGaAs semiconductor lasers. Suitable rubidium beams can easily be produced with effusive ovens, but many ex...

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...
