[H] italics?

[Function]

Hello

It's commonly known that quantities are put in italics, whereas their units aren't.

I'm in doubt whether to put "[¹H]", being the concentration of hydrogen protons, in italics or not. Would I then put the whole thing in italics? Just the square brackets? Or just the ⁽¹⁾H?

• [¹H]
• [¹H] vs. [¹H]
• [¹H]

To be honest, whichever one is correct, the last one looks the least frustrating.

Thanks;

Function
