Dear everyone,

First, Please accept my sincere wishes for the New Year. I hope you will continue to enjoy good health.

Second, I have some questions to consult with you about the geometry optimizing.

As we know, in some other softwares, i.e., Gaussian03,Dmol, after optimizing one molecular or cluster geometry, we could judge the stability of the molucular or cluster through analyzing the vibration frequency. However, if we optimize one molecular or two-probe system in ATK , how do we verify the stability of the optimized structure.

Thanks!
