 Dear all,
   I used qst2 to find transition state. The input file is as follows:
 %mem=500mb
 %nproc=4
 #p opt=(qst2,maxcycle=500) freq mp2/6-31g(d) geom=connectivity scf=maxcycle=800
 The job failed. The error message is as follws:
 Iteration100 RMS(Cart)=  0.00007251 RMS(Int)=  0.18458671
  New curvilinear step not converged.
  ***** Convergence failure in GTrans *****
  Try using 3 structures as input for
  QST transition state search
