ab initio calculation: NMR shielding tensor



 Dear All,
         I wonder if someone have performed ab initio NMR
 shielding tensor calculations on paramagnetic compounds by means of GIAO
 or CSGT methods.
        Could you point me some paper concerning the argument? or could you
 write me your knowledge about the reliability of GIAO and CSGT NMR
 shielding tensor calculations on paramagnetic molecules?
        I will summary all the answers.
        Thank you
  Alessandra
