Hi everybody,(adsbygoogle = window.adsbygoogle || []).push({});

My post today is about Molecular Symmetry group (MS) for non-rigid molecules. I read from this excellent work (Longuet-Higgins), that MS is obtained by selecting only feasible operation from Complete Nuclear Permutation Inversion Group (CNPI).

My question is,

As I have a quite big non-rigid molecule (##C_{28}H_{20}N_2##) and I know its two equilibrium geometric equivalent configurations, so, is there a kind of software or special program that can help me to compute its MS group?

Thank you very much everybody.

Konte.
