High Symmetry and GIAO

[Ivan Aprahamian <ivan_at_pob.huji.ac.il>]

 To whom may it concerned
I have run an NMR calculation on Gaussian98 using B3LYP/631G*, on a
 compound with C5V symmetry.
 But the NMR results i am getting, fit a compound with Cs symmetry,
 although
 in the computation the full point group is C5v. The Cs symmetry is the
 Abelian subgroup - and i think for some reason this is why i am getting
 the
 "wrong" results.
 Is there a way to bypass this problem?
 thank you in advance
