Junmei and all,
I'm running ANTECHAMBER and LEAP to try and generate GAFF parameters
for a variety of small molecules, and I keep getting warnings about
missing improper torsions for pretty much everything with a nitro
group (for example, 1-nitrobutane gives me a warning about "No sp2
improper torsion term for c3-o-no-o".
Can anyone shed some insight here? Why is there a nitro type but no
improper torsion for these?
Thanks,
David
