N2+ cation 2PIU state by G98?



 Dear All,
 I am puzzled by some of the data in G1 database. For example, how to make
 a G98 input file to calculate the energy of N2+ cation to retrieve the
 ionization potential of nitrogen by G1 method? Since there are two
 electronic states for N2+ cation of the same multiplicity (2PIU and
 2SGG), I wonder how to specify each of them by G98 input.
 Thanks in advance.
 Sincerely yours,
 ZX
