how to do the excited calculation with ADF package?



hello,
 Does someone know how to do the excited calculation in ADF package?
 For example, i want to deal with the transition metal complex:[NH3)5Ru-
 Pyrazine-Ru(NH3)5]5+, the ground state is calculated to be a single
 electron occupying in the Ru-dxz orbital, and zero electron occupying
 Ru-dz2 orbital, then i want to get the excited state with exciting the
 electron in Ru-dxz orbital to Ru-dz2 orbital? how to get the excited
 state?
 Thank you very much!
