Determining the order of a molecular point group (2011)
AuthorsWilliamson, B.E.show all
Conventional methods of identifying the point group of a molecule require skills in finding symmetry elements and operations. A useful aid to error checking is an ability to determine the order of a group purely from its label. To this end, Curnow has promulgated a set of simple empirical rules. In this article, Curnow’s rules are substantiated using simple geometric considerations from the basis of point group generators. The proof is provided in a form that will be accessible to undergraduate chemistry students and their teachers
