Abstract
•Wavelengths measured using commercially available ICP emission spectrometer•First wavelength and wavenumber measurements of some E2 lines of Ba +, Ca +, Sr +•Evidence for small plasma shifts in the wavenumbers of Ba + and Sr +
Forbidden (electric quadrupole, E2) transitions of the type ns2S1/2–nd2D3/2 and ns2S1/2–nd2D5/2 in the ultraviolet spectra of singly ionized Ca, Sr, and Ba (with n = 4, 5 or 6 for Ca, Sr, and Ba, respectively) have been observed in the emission spectrum of an inductively coupled argon plasma. Wavelengths and wavenumbers of the six lines are reported and the values are in good agreement with those expected from literature data for the energy levels involved.
