error in dscf with ghost atom (with basis)

Dear users!

I am trying to compute the vertical spectrum of bithiophene using the additional rydberg orbitals centred on the centre of charge of the molecule, which in his case is point 0. 0. 0. (C2h symmetry). Therefore I placed there the ghost atom q for which I added the diffuse rydberg orbitals to the basis set (in the file basis).

However, dscf program crashes with the message:

fatal error in grinp.
dscf ended abnormally

program stopped.

I have tried to find the reason in the manual files, but unfortunately without success.
I would greatly appreciate some help, cos I am quite at a loss.

P.S.: the valence basis set is aug-cc-pVDZ

Hi,

q is a dummy atom not a ghost atom. You would have to select a defined element in order to have a defined DFT grid, e.g. he, and then set the charge to zero.

Cheers,
