I am trying to find a transition state using QST2 with b3lyp, but I am getting the following error:
"New curvilinear step not converged.
***** Convergence failure in GTrans *****
Try using 3 structures as input for
QST transition state search"
The input line is as follows:
# opt=qst2 b3lyp/6-31g(d) nosymm geom=connectivity SCF=tight
Herewith I have attached my input file.
If you could please let me know how to solve this error.
Thank you.
