 * Symbol possible vote.svg Article is new enough, long enough, referenced throughout, and neutral.  Hook is present and cited. Can't myself see the hook and other refs beyond the abstract; they are accepted as supportive and non-plagiarism on the basis of AGF. Hook is short enough. QPQ performed. Almost good to go. Would only suggest: a) that nom add the words "in the ground state" to the hook, as that is a limitation of the hook statement that is reflected in the text; and b) that, though this does not impact approval at DYK AFAIK, wikiprojects be added on the talk page. Also -- the article doesn't have a real lede -- I would suggest a lede that summarizes the most important aspects of the  article, as described by wp:lede, be added prior to what are now the first two paras, which should in whole are in large part be the first full section of the article.

 * Symbol redirect vote 4.svg Somehow I did not notice this review! I have reorganised the lede now.  Also a project is on the talk page. I have also added quite a bit more text so more checking for citations, which are there, may be warranted. Here is your proposed alt hook
 * alt1 ... that the helium dimer is the largest molecule in the ground state made from two atoms?
 * I did not put "ground state" in my proposed hook as I would not expect our readers to not really know what it meant. It is only molecules in some kind of super excited state, excimers, that much have a puffed up electron shells that make them bigger than the helium dimer.  These would be Rydberg molecules.  These excimers are not indefinitely stable, unlike the helium dimer in cryogenic conditions.  Graeme Bartlett (talk) 03:31, 20 February 2015 (UTC)
 * Symbol confirmed.svg Points addressed, in Alt 1. One minor point is that ground state IMHO should be linked, as ... as pointed out ... readers will not be familiar with the term. Epeefleche (talk) 08:15, 20 February 2015 (UTC)
