The Li2+ion is hydrogenic and has a Lyman series at 740 747 cm3, 877 924 cm-1, 925 933 cm-1, and beyond. Show that the energy levels are of the form -hcRln2 and find the value of R for this ion. Go on to predict the wave numbers of the two longest-wavelength transitions of the Balmer series of the ion and find the ionization energy of the ion.
