In particular, we will look at transitions between the sub-levels of the rubdium rubdium transitions in ev 5s–5p. Rubidium can very easily get ionized and hence it is used for ion engines, but it is still less efficient than that of Caesium. A rubidium standard or rubidium atomic clock is a frequency standard in which a specified hyperfine transition of electrons in rubidium-87 atoms is used to control the output frequency.
