Run TTRCN on them and replace the Ni parameters in the rcg-file with the Mn parameters. 4.Run TTRCG, TTRAC and TTBAN on the Mn files. 5.Plot the result 6.Modify exct1.ban in order to calculate 1.The pure 3d 4 ground state 2.The pure 3d 5 ground state 3.The spectrum of LaMnO 3 Exercise: Charge Transfer on Mn 3+
