Where to put the dot on radicals (notation)

Click For Summary

Discussion Overview

The discussion revolves around the notation of radicals in chemical formulas, specifically the placement of dots in representations like ⋅H and ⋅OH. Participants explore the implications of different placements in academic writing and reporting.

Discussion Character

  • Debate/contested

Main Points Raised

  • One participant questions the significance of dot placement in radicals, noting inconsistencies in various papers.
  • Another suggests that the choice of dot placement may depend on the preferences of journal editors, indicating a lack of standardization.
  • A different viewpoint proposes that both ⋅H and H⋅ are acceptable, but cautions against using OH⋅ as it could mislead regarding the radical's position.
  • One participant raises a specific scenario regarding the notation for spectral emission from a radical, suggesting ⋅OH* for clarity.

Areas of Agreement / Disagreement

Participants express differing opinions on the correct placement of dots in radical notation, indicating that no consensus exists on a standard practice.

Contextual Notes

Limitations include the absence of a universally accepted guideline for dot placement in radical notation, and the discussion reflects varying interpretations based on context and audience.

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?

thanks for any advice

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...
