They're the type of tools I'm looking for but they don't produce any conformers for N2H4 and C2H6. Thanks, Scott On 20 March 2014 15:49, Pascal Muller wrote: > Hi, > > > > > > Thanks Igor but that was just an example of how you could find the minima >> from input structures, I am interested i

Thanks Igor but that was just an example of how you could find the minima from input structures, I am interested in generating the conformers using openbabel. Best wishes, Scott On 20 March 2014 15:21, Igor Filippov wrote: > I don't think openbabel can do DFT or any kind of ab initio quantum

I don't think openbabel can do DFT or any kind of ab initio quantum chemistry. Regards, Igor On Thu, Mar 20, 2014 at 11:15 AM, Scott McKechnie wrote: > Ethane (C2H6) and hydrazine (N2H4) have distinct minima that are separated > by rotational barriers. Depending on the input structure, a geome

Ethane (C2H6) and hydrazine (N2H4) have distinct minima that are separated by rotational barriers. Depending on the input structure, a geometry optimization (for instance in DFT) will bring you to one of these minima. I am interested in generating such conformations in a systematic way. Best wishe

Hold on, what is to rotate in a C2 or N2 molecule? And what would be a conformation for a diatomic structure aside from the trivial one??? It's just two atoms (not including hydrogens) with a single bond between them or did I misunderstand the question completely? Igor On Thu, Mar 20, 2014 at 10
