[edit] Review

The list of compound names needs a thorough review by somebody knowledgeable about chemistry. Thank you. — RJH 19:46, 6 Nov 2004 (UTC)

It also absolutely needs references to who found this molecule and when. For example, for Glycine there is extensive information in the article. Paranoid 20:14, 11 Nov 2004 (UTC)
Every entry now has a reference. — RJH (talk) 18:35, 13 February 2007 (UTC)

whould sub atomic particles and parts of atoms fall under this catigory?

Probably not. Molecule implies multiple atoms. In any case, I'm going to give this article a good once-over and check some of these. I took a quick cursory glance...You have Aluminum Fluoride as AlF, but aluminum fluoride is AlF3. EagleFalconn 00:01, 25 Nov 2004 (UTC)

[edit] H3+

I've taken a look at the article. You've got a problem: According to the rules of computational chemistry the molecule H3+ can't exist. You've got both electrons existing in standard s orbitals, 1.333 of them are in anti-bonding orbitals. The molecule would never exist, not even for picoseconds. H3 on the other hand, would exist though only just barely and probably only under exceedingly high pressures. I would sugest attempting to find some alternative resources for this information to check accuracy. EagleFalconn 15:57, 29 Nov 2004 (UTC)
You may be right, but there are a number of published papers on the topic. References:
&c. — RJH 22:05, 20 March 2006 (UTC)
Just a quick note: this remains one of the great unsolved problems in astrochemistry. The H3+ molecule has been unequivocally observed many times, yet still cannot be properly accounted for in any chemical model. Yes, it shouldn't exist, but it does so we're obviously missing something! Modest Genius talk 16:43, 22 April 2007 (UTC)
See "protonated molecular hydrogen" which covers the topic in great detail. — RJH (talk) 14:47, 23 April 2007 (UTC)

[edit] History article

  • I really warmed to the idea of this article since for years I have been fascinated by the discovery of organic molecules in the interstellar medium. I think this article would be greatly improved by some information on the various discoveries, hypotheses on formation / origin of these molecules, perhaps even indications of distribution and concentrations. rturus 00:39, 12 Dec 2004 (UTC)
    • Great. But this is just a listing. A dedicated history would be better served on a separate article page. Thanks. — RJH 22:00, 20 March 2006 (UTC)
    • P.S. A good source looks to be: Interstellar and Circumstellar Species.

[edit] GA failed

According to this criteria, the article fails, since GA does not cover lists. Consider taking it to peer review and straight to FAC. --Nehrams2020 18:15, 12 February 2007 (UTC)

Well, since there isn't actually criteria for images, portals, and lists, then it couldn't of failed any of them per se, and they aren't really valid candidates, so i've removed the template. Homestarmy 18:56, 13 February 2007 (UTC)
Sorry. I put the page up as a FLC instead. — RJH (talk) 22:14, 13 February 2007 (UTC)

[edit] molecular oxygen has been discovered

http://www.physorg.com/news94210066.html Thanks, CarpD 4/2/07

Thank you. — RJH (talk) 19:48, 2 April 2007 (UTC)

[edit] Some more

  • HCP Phosphaethyne [1]
  • C4H- [2]

Modest Genius talk 19:56, 2 June 2007 (UTC)

Thank you for the additions. I've added them to the appropriate tables. — RJH (talk) 18:20, 4 June 2007 (UTC)

[edit] Largest negatively charged molecule

http://www.nrao.edu/pr/2007/biganion/

It looks like negatively-charged octatetraynyl (C8H-) is already in the table. Thanks. — RJH (talk) 14:38, 24 July 2007 (UTC)

[edit] Sort order?

Does anybody know the appropriate sort order for tables such as these? Up until now I had been sorting based on the molecular formula. Thanks. — RJH (talk) 16:12, 14 August 2007 (UTC)

I've added the "sortable" class so that users can automatically sort the lists by any of the three columns. Hope that helps. Mike Peel (talk) 14:43, 9 March 2008 (UTC)
Yes that helps. Thank you.—RJH (talk) 16:41, 9 March 2008 (UTC)

[edit] Neutron stability in space

Who is it that knows that that the neutron is unstable in space? Since the atoms, which were accumulated in a three dimensional process in space and have neutrons as a major constituent, and since there is considered to be a lot of unradioactive and unexplained matter in space, why couldn't there be a lot of neutrons in space taking part in the accumulation process. And with all due respect to the quark theory, the primary process might be postulated to be the accumulation of gravitons into neutrons. I dont have any references about this.

This page is devoted to discussions of the Wikipedia article on molecules in interstellar space. You might have better luck getting an answer to your question if you post it on the free neutron talk page. I note that that page gives t1/2 = 15 minutes for neutron decay, and that a reference is provided. That's where I would start. Good luck! - Astrochemist (talk) 12:27, 19 May 2008 (UTC)
