Where to put the dot on radicals (notation)

AI Thread Summary
The placement of the dot in radical notation is a topic of debate among researchers. While some prefer the dot before the symbol (⋅H) and others after (H⋅), both are generally acceptable. However, clarity is crucial; using OH⋅ can imply the radical is on the hydrogen rather than the oxygen, which is misleading. For spectral emission discussions, using ⋅OH* is recommended for precision, ensuring the radical's position is clear. Consistency in notation is also emphasized, as it may depend on the preferences of journal editors.

This may seem a bit pedantic but I'm writing a report and have radicals in it and notice that some papers put the dot in different places, so my question is does it matter where you put the dot?

First choice (mixed) --- bad juju.
Second, or third (consistent), depending on Journal editor.

In my opinion, ⋅H or H⋅ are both fine. I would avoid OH⋅ because it makes it seem like the radical is on the hydrogen, where the radical should instead be on the oxygen (as indicated by ⋅OH).

Ok, many thanks!
 
hmm so if you were talking about the spectral emission from a radical would you write ⋅OH* to be more precise, and not...

I want to test a humidity sensor with one or more saturated salt solutions. The table salt that I have on hand contains one of two anticaking agents, calcium silicate or sodium aluminosilicate. Will the presence of either of these additives (or iodine for that matter) significantly affect the equilibrium humidity? I searched and all the how-to-do-it guides did not address this question. One research paper I found reported that at 1.5% w/w calcium silicate increased the deliquescent point by...
