Talk:Rotational spectroscopy
From Wikipedia, the free encyclopedia
[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.
[edit] figures required
Need to add some figures, explaining the spectrum. Also a section for experimental determination and applications.
I've added a figure for a linear molecule, but some explanation of the Q-branch transitions that are sometimes observed is needed, and I'm not really qualified to do so. I have a scan of a spectrum recorded in my university labs on a FTIR machine of an HCl / DCl mixture. Does anyone know if there would be any problem with me putting this up?

- I've noticed that the rotational energy levels in the figure (Image:Vibrationrotationenergy.svg) become progressively closer with increasing J. It is my understanding, however, that the energy level gap between successive levels grows as J increases.--GregRM (talk) 23:54, 15 February 2008 (UTC)
