Hi,
yes, it is possible.
if you use 'native' input:
Basis
H.6-31G.....
H1 -1.0 0.0 0.0
End of Basis
Basis
H.6-31G*.....
H2 1.0 0.0 0.0
End of Basis
if you use 'xyz' input, you can use labels (element name plus underscore and a label:
e.g. H_small)
Coord
2
hydrogen molecule
H_small -1.0 0.0 0.0
H_large 1.0 0.0 0.0
Basis
H_small.6-31g*,H_large.6-31g
or, use basis sets directly in the coordinates:
Coord
2
hydrogen molecule
H.6-31g* -1.0 0.0 0.0
H.6-31g 1.0 0.0 0.0
