Diatomic and Triatomic are also taken from greek. It makes absolutely no sense to keep those but call all the ones 4+ Four atoms, Five atoms, Six atoms etc. instead of Tetratomic/Quadratomic, Pentatomic, Hexatomic, etc. Can someone tell me why? It makes no sense to stop at triatomic and not continue the pattern. 24.150.136.68 (talk) 00:06, 13 April 2017 (UTC)

:Diatomic and triatomic are in common use. Those others are not, and I suspect a writer here is using Wikipedia to promote their use. The point is not whether the terms are from Greek, but that they are not used as such in English much. Graeme Bartlett (talk) 00:56, 13 April 2017 (UTC)

::{{done}} - FWIW - yes - agreed - common use is preferred - hope this helps - Enjoy! :) Drbogdan (talk) 02:26, 13 April 2017 (UTC)

:We certainly shouldn't use the Greek forms for four or more atoms, which very few readers would understand. Diatomic and triatomic are sufficiently common that it seems fine to use them, but I'm not opposed to 'two atoms' and 'three atoms' either. Modest Genius ^talk 20:26, 13 April 2017 (UTC)

Papers can also contain errors - linear C3H can be called propynylidyne, but in chemical nomenclature simply adding cyclo in the begining to name a cyclic isomer and calling it a deal is not OK. If authors of a paper made an arbitrary name like "housane" then OK, but making a misleading name - cyclopropynylidyne would be correct for C3 molecule - is not acceptable. It could be mentioned in the table as a name which is used, but should be highlighted as incorrect. In general, this practice with adding just the names from papers is unacceptable, especially in a featured article. There is something called IUPAC, isn't there? All names should be checked and the ones like "heptatrienyl radical" for C7H (this one is much worse) either eliminated altogether, or marked as wrong if they are in actual use (not just used in single paper).

:This is an encyclopaedia, not a chemistry textbook. We report what reliable sources are saying, we don't correct them just because we think they made a mistake (see WP:VNT). If reliable astrochemistry sources are using name X, then name X is what we should report in this article, regardless of whether it meets IUPAC rules. This article has followed the original detection paper for convenience and ease of verification; if there are specific examples where the astrochemistry literature has switched to a more standard name in subsequent papers I agree it should be changed (and an additional reference added for the new name). We shouldn't rename entries just because you dislike the one used in the discovery paper. Modest Genius ^talk 11:31, 2 November 2020 (UTC)

FWIW - (For being aware only of newly published relevant studies - not necessarily to incorporate into the main article) - On 8 July 2022, astronomers reported the discovery of massive amounts of prebiotic molecules, including for RNA, in the galactic center of the Milky Way Galaxy.{{cite news |last=Starr |first=Michelle |title=Loads of Precursors For RNA Have Been Detected in The Center of Our Galaxy |url=https://www.sciencealert.com/scientists-have-found-a-bunch-of-rna-precursors-in-the-galactic-center |date=8 July 2022 |work=ScienceAlert |accessdate=9 July 2022 }}{{cite journal |author=Rivilla, Victor M. |display-authors=et al. |title=Molecular Precursors of the RNA-World in Space: New Nitriles in the G+0.693−0.027 Molecular Cloud |url=https://www.frontiersin.org/articles/10.3389/fspas.2022.876870/full |date=8 July 2022 |journal=Frontiers in Astronomy and Space Sciences |doi=10.3389/fspas.2022.876870 |accessdate=9 July 2022 }} - Stay Safe and Healthy !! - Drbogdan (talk) 13:09, 10 July 2022 (UTC)

:These seem to all be molecules that were already known in the ISM and are already listed in our table. The only complication is that they report "Cyanopropyne (CH3CCCN)" while our table reflects the previous publication that called it Methylcyanoacetylene (H3CC2CN); as far as I can see those are the same molecule. This paper has found a combination of nitriles in the same molecular cloud, so can do some more astrochemical modelling, but they're not new interstellar molecules.

The entry for MgH+ [https://en.wikipedia.org/w/index.php?title=List_of_interstellar_and_circumstellar_molecules&diff=prev&oldid=374280165 was added] in 2010 by {{user|150.203.35.113}}. The citation is to a broad textbook on the ISM, with no page number, which doesn't seem to be available online. MgH+ isn't included in other reliable lists of interstellar molecules (Astrochymist, Cologne, McGuire 2018) and I searched ADS for the original paper without finding anything. The closest was a non-detection of neutral MgH [https://ui.adsabs.harvard.edu/abs/1987A%26A...188..155C/abstract]. For now, I've tagged this entry as dubious, but I suspect it's spurious.

:The same IP user added a bunch of other entries, including NO+ and CN+ which are cited to the same textbook. I haven't looked into those yet. Modest Genius ^talk 16:13, 15 May 2025 (UTC)

When the dab at FECN (disambiguation) is deleted, the redirect should be added redirect|FeCN|network congestion|FECN per WP:ONEOTHER and WP:DIFFCAPS (per history). That is, if that editor allows others to edit this article? Widefox; talk 22:30, 22 May 2025 (UTC)

• {{done}} - the place to discuss the dab is at Wikipedia:Articles for deletion/FECN (disambiguation). The place to discuss changing the MOS for such hatnotes / dabs is at the links given. Widefox; talk 13:45, 24 May 2025 (UTC)
