I have a variable with a subscript describer P_{\rm 1S}
I'd like to square it.
First a style question: is (P_{\rm 1S})^2
or P_{\rm 1S}^2
better? The programming part of the problem is that the latter aligns the superscript vertically above the subscript, I would like the power to be aligned further to the right distinct from the variable and its descriptors. Is there a simple way to do this?
x^a{}_b{}^c
