Math & Science ⇒ mhchem package

[danj]

Hi All,

A little help with the above package would be great.

I am writing a paper using the achemso style file from the ACS.

In the past I have used chemsym for formulas, but the ACS prefer mhchem. I am having trouble trying typset 1H or 13C, where both the 1 and 13 are superscript.

I have tried \ce{^{1}H}, \ce{^1H} amongst other things, even the example (\ce{^{227}_{90}Th+}) in the mhchem documentation doesn't run giving an error message of

Argument of ^ has an extra }.
<inserted text>
\par
1.31 \ce{^{227}_{90}Th+}

Runaway argument?
! PAragraph ended before ^ was complete.
<To be read again>.

log file attached.

Got it working, not sure if is the most elegant way, or if it is the way the author/developer intended, but it works.

\ce{$^{1}$H}

I can't comprehend the problem because the code below compiles flawlessly. But also with the example you provided I only get some font warnings (after commenting the rather old chemsym package).

Perhaps a matter of outdated packages. With the \listfiles command I obtain the file list shown below (on my Linux system).

I think you should not load so much packages because as you can see, the achemso class does that on its own. Check those dependencies in the class manual.


Best regards and welcome to the board

As localghost says, you should keep down extra packages loaded with achemso. Those that the class loads will work when you submit to the ACS: I've had lots of correspondence with them to make sure of this. I'd also suggest avoiding making changes to the settings unless you really need to alter things like sections, abstracts, etc. The journal files (hopefully) have the correct settings for each journal.

On the mhchem issue, I notice that chemsym is not in my TeX Live set up, so is almost certainly not on the ACS system. I wonder if the problem you saw was due to loading both mhchem and chemsym. For me, the following is fine:

Code: Select all

\documentclass[journal=joceah,manuscript=article]{achemso}

\end{document}

Thanks for your replies. I have a lot of data which will need re-editing (and relies on the chemsym package) before I submit the paper.

I will try your suggestions once I have re-edited the data using the mhchem package.
