 I am trying to optimize a structure with opt=(tight,maxcyc=100).
 But the geometry is not converging. After 4 converging point
 it comes back to the original point.
          Item               Value     Threshold  Converged?
  Maximum Force             .000018      .000015     NO
  RMS     Force             .000008      .000010     YES
  Maximum Displacement      .009113      .000060     NO
  RMS     Displacement      .003305      .000040     NO
 Kind of trapped in a loop. I tried to reoptimize the geometry
 by changing little. But it doesnt help. In another probelm,
 I am getting YES flags for the optimization but in the frequency
 calculation I am getting the RMS as NO. I would appreciate
 to receive your comments. Thanks. Artiben.
