Finding STO3G Parameters for H,He,C,N,O

[aihaike]

Dear all,

I need the parameters for the STO3G basis set H,He,C,N,O.
Where can I get them?
Thanks,

Eric.

But note that STO-3G is /NOT/ a real basis set, it cannot be used for any calculations which aim to mimic real molecules in some way or another (in other words: it is very very very bad, even for a minimal basis set). So unless you require it to debug an integral program or to reproduce some numbers from other people I would advice you to use a different one.

Yeah, I'm aware about that.
I'm just want to write a little HF code.
Thanks for the reply.
