[edit] This article contains the following sentence:

For convenience molecules are divided into four classes: (1) Linear molecules (2) Symmetric Tops. (3) Asymmetric Tops. dealing with each in turn:

Clearly, only three classes are named (and only these three are discussed). However, a fourth class must also be considered, namely (4) Spherical Tops. A section on spherical tops should be added here.

[edit] page needs dramatic rewrite

For some reason, this page seems really lame. It really needs to be updated to offer a more structured description of the topic. Suprisingly bad.

I found some misinformation concerning the P branch and R branch (it has been corrected). I haven't had time to look through the rest of the article, though I think that the validity of the information should be checked-- consider the mixup that I found and other possible mixups in the article.
