All,
I have optimized Aniline (C6H5NH2) using different methods and basis
sets, and despite Aniline is a single conformer compound but my optimization
falls on a transition state with negative frequency.
What does it mean?
Does Aniline have another conformer?!!
How can I solve this problem in
G09? It must have no negative frequency.
