N, principal quantum number

The energy of any one-electron species in its nth state (n = principal quantum number) is given by E = —BZVn2, where Z is the charge on the nucleus and B is 2.180 X 10 18 J. Find the ionization energy of the Li2+ ion in its first excited state in kilojoules per mole. 

Here n = principal quantum number, IP = ionization potential, f = orbital exponent and C = d-orbital coefficient. To mimic self-consistency in adsorption studies Pt ionization potentials are increased by 1.5 eV, O and C ionization potentials are decreased by 1.5 eV, and O exponents are decreased by 0.1 eV.
