@DMacks:I am (i) adding content (open source example from Org Syn), (ii) removing spam (see User talk:Vikingo999), and improving the wording, (iv) correcting overstatements (photoisomers are not used in any device, and the claim was unsupported). I am going to remove a lot of the spam inserted by the ref spammer Vikingo999. A public service. And I have only slightly begun on reworking this article, an area where I have expertise. --Smokefoot (talk) 18:42, 12 January 2020 (UTC)

Sounds good. Ref-spamming and over-stating what refs actually say has actually been demonstated are no-nos. I'm an structure and organic-mechanisms person, not so much about metal-complexes. DMacks (talk) 03:59, 13 January 2020 (UTC)

@Wiki Chemistry: you will want to tone down the rhetoric substantially. We are here to collaborate not attack and are required to assume good faith of others' work. Just because "anyone can edit" doesn't mean everyone's edits are equally acceptable or guaranteed to survive--there are standards and guidelines here just as on any other medium. Multiple editors dispute the content (itself, or relevance to where you insert it) and sourcing of many of your edits. Several have noted you have a particular affinity for Rostami's work...what is your connection to that reasearch group? DMacks (talk) 18:52, 12 January 2020 (UTC)

§ Examples organization

Should we try to distinguish among the different types of isomerization, rather than just dumping a bunch of examples? I propose (in no particular order, based on File:Photoisomerization_.gif among other sources of inspiration for the effects of the changes):

1. Single-atom changes
   1. High/low-spin
   2. Center-vs-ligand or two-distal-atoms redox?
2. Sigma-only changes (mostly related to coordination complexes)
   1. Octahedral (M/P) and square–planar
   2. Linkage isomerism
3. Pi-only changes (E/Z)
4. Pericyclic reactions (see that article for a table of different subtypes...probably have photo variants of most of them)

Any plan sounds better that the hodge-podge. I have been just inserting big reviews and English-free figures to show user:Wiki Chemistry what good components of an article might look like as we coalesce this thing. My main modifications of the above list might be

1. that the topic is probably mostly of interest to organic chemists, so we might start with their stuff.
2. I am going to hunt down the retinal (or whatever it is) cis-trans isomerization related to vision, since that seems to be a big deal.
