LaTeX forum ⇒ Math & Science ⇒ mhchem | Atomic Level Topic is solved

[niles]

Hi

I wish to write the following atomic level: 5s^2 1S_0. Usually I use mhchem for these things (MWE):

Code: [Select all] [Expand/Collapse] [Download] (untitled.tex)

\documentclass[11pt]{article}
\usepackage[T1]{fontenc}
\usepackage[version=3]{mhchem}
 
\begin{document}
\ce{5s^2 ^1S0}
\end{document}

However it doesn't work very well, as the superscripts are not at the same height due to one 's' being uppercase and the other lowercase. Do You suggest another package for me to use?


Best,
Niles.

You could use the chemmacros package which has the very similar command \ch:

Code: [Select all] [Expand/Collapse] [Download] (untitled.tex)

\documentclass[11pt]{article}
\usepackage[T1]{fontenc}
\usepackage{chemmacros}
 
\begin{document}
\ch{5 s^2\,^1S0}
\end{document}

Thanks for that, that is very helpful. I have another question in the same subject: I want to write a state 3^P_J, but when I use

Code: [Select all] [Expand/Collapse] [Download] (untitled.tex)

\documentclass[11pt]{article}
\usepackage[T1]{fontenc}
\usepackage{chemmacros}
 
\begin{document}
   \ch{5 s^2\,^3PJ}
\end{document}

it does subscript the "J". Is there a way to remedy this?

Thanks for Your help in advance.


Best,
Niles.

I do not understand what you mean exactly. This looks exactly as I would expect it to:

Code: [Select all] [Expand/Collapse] [Download] (untitled.tex)

\documentclass[11pt]{article}
\usepackage[T1]{fontenc}
\usepackage{chemmacros}
 
\begin{document}
 
\noindent
\ch{5 s^2\,^3PJ} \\
\ch{5 s^2\,^3P_J} \\
\ch{5 s^2\,^3P "\_" J}
 
\end{document}

Thanks, I forgot the underscore (_) in my example. It works!


Best,
Niles.
