Text Formatting ⇒ Large default size

[niles]

Hi

Please see my MWE:

Code: Select all

\documentclass[a4paper]{article}
\usepackage{amsmath} 
\usepackage[sc]{mathpazo}
\usepackage{mhchem}
\begin{document} 
For the transition $\left| {\ce{^1S0}} \right\rangle$ one sees \ldots
\end{document}

I am unhappy about the large size of

Code: Select all

$\left| {\ce{^1S0}} \right\rangle$

. I think it is because of the font mathpazo, but is there a way to reduce it? If I use the standard font (i.e. comment out mathpazo), then it looks OK.

Best,
Niles.

Hi Niles,

it seems there are at least two reasons:

• the mathpazo font is higher
• mhchem raises the indexes

Since you already noticed the first point, let's have a look at the second one. Compare your mhchem formula to a formula made with standard indexes:

You don't want to change the font, and I guess you don't like to change the way mhchem works with indexes, because it does additional vertical alignment. A workaround would be using \big instead of \left and \right:

Code: Select all

For the transition $\big|{\ce{^1S0}} \big\rangle$ one sees \ldots

In any way, I recommend to define a macro for this expression and use the macro in the text. This way you can easily adjust it later, if desired.
