Hello
everyone:
For a nonlinear
N-atom molecule there are 3N-6 internal degrees of freedom, of course.
However, for a point group-constraint molecule,
such as C2v H2O, there are only 2 independent degrees of freedom.
So, is there a systematic way to determine the number and the contents of
independent degrees of freedom of an arbitarily symmetry-constraint molecule? I
heard that some knowledge like Polya theorem are requied, but I am not sure. It
will be better if some reviews can be
reccommended.
Thank you in
advance. Any suggestions will be
appreciated.
Best
regards!
