Rubidium emission spectrum
WebbThe spectrum of ionised rubidium from a laser-produced plasma has been photographed in the 250-500 AA region. Lines arising from 4p-5s and 4p-4d transitions in ion stages Rb IV to RB IX were found to dominate the spectrum. Some 4p-5s transitions in Rb VI together with the strongest lines of the 4p-5s in Rb V were identified by isoelectronic comparison and … http://webmineral.com/help/FlameTest.shtml
