Computing molecular symmetry group for non rigid molecules

  1. Mar 16, 2017 #1
    Hi everybody,

    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.

    I don't know of any dedicated program for CNPI. However, there are some mathematical programs to deal with subgroups of large permutation groups and the like:
