\nbsp trick to get prefixed superscript to work?

\nbsp trick to get prefixed superscript to work?

I saw an earlier discussion about Emacs/org-mode superscript and subscript
behavior. My issue is I want to do a chem isotope of an element. In
standard Latex format I would do this:

$^{147}$Pm  or leaving off the $ and turning on Emacs' display of UTF-8 (
C-c C-x \ ) just ^{147}Pm

but it doesn't work in either Emacs or org-mode, however

Pm^{147} does, i.e., putting the super-/subscript /after/ Pm. Also,

$^{147}Pm$ does work, although it converts the Pm into italicized text upon
export. Also

\nbsp^{147}Pm works in both Emacs and org-mode, but upon standard export to
HTML, it works in the TOC and down in the actual text, but not in the
"Contents" section (not used in Latex export).

Apparently, chemists cannot do Emacs and/or org-mode when they want to
prefix the super- bzw. sub-script without a kudge?

This seems to work fine for me both for latex and html (with MathJax)
export:

--8<---------------cut here---------------start------------->8---
* Dating with \(^{14}\)C.

Dating with \(^{14}\)C.
--8<---------------cut here---------------end--------------->8---

I've recently have had to start writing papers with significant amounts
of chemistry in them.  I simply use the mhchem package which supports
all types of chemical notation...  org is quite happy with it for simple
entries although you may need to @@...@@ escape more complex entries.

However, if you wanted something portable, i.e. that could export to
other targets, then this won't help you.  Sorry!

I think what Eric is referring to is:

#+latex_header: \usepackage[version=3]{mhchem}

@@latex:\ce{^{147}Pm}@@

that exports for me.

\nbsp{}^{147}Pm also seems to work, but might put an extra space in.

you might prefer \phantom{}^{147}Pm

Or using the zero-width char (via the predefined entity \zwnj in Org)?
