Step: 127

Next example we want to determine the point group of benzene.

1. Type of the axis of rotation:
With the benzene molecule several axes of rotation are present, i.e. except C₆ axis perpendicularly to the molecule plane and some C₂ axes in the molecule plane. As describes in step 124 , we must select one of these axes as reference axis. Which is that? In which part of the algorithm are we therefore?

Go now to step 128 !
