 Some limitations of current implementation are listed below:
 
-* The EE-RADC code does not support calculating oscillator strengths.
-  This property can be computed using the EE-UADC code (i.e., by using
-  the UHF reference) for a closed- or open-shell molecule.

 * The EE- and IP/EA-RADC codes compute only the states of lowest spin:
   S = 0 (singlet) and S = 1/2 (doublet), respectively. Using the
   corresponding UADC code allows to compute excitations with ΔS = 0,
