I like the precipitate sign on the P20 of chemformula official documentation. But I can only get like this on my own computer by the example code:

Ugly sign

What should I do?

    Maybe: \usepackage[libertine]{newtxmath} Please provide an image of what you want and of what you have with the code you needed to get there in your post. Try to leave external links from your post, as we can not be sure where they lead to. Thanks.

  • You are welcome. The optional libertine can be left away, I guess. Just copied that line of code from Clemen's chemformula_en.tex. The loading of this package will possibly change other symbols as well. Just read its manual. The arrow you were showing above was from Latin Modern which is default. Just fyi.

1 Answer 1


The author of the chemformula package loads the package newtextmath in his documentation which changes the arrows (and most probably other symbols). Your current result is an arrow from the font Latin Modern which is the default for LaTeX. Please see my MWE for the desired version. (For future post please always post such an MWE which makes it easier for us. Please change the title of your post to something more telling than no! Thanks)
