It helps you to create MO diagrams directly in an interactive online editor. It outputs the relevant code that you just have to copy into your project.


Features

  • Interactive Editor: Design MO diagrams visually without writing hundreds of lines of PGF/TikZ code.
  • Integration: Generates ready-to-use code blocks compatible with the provided mohelper package.
  • Scientific Accuracy: Built-in support for Symmetry Groups, Degeneracy, and proper Electron Configuration.

How to use it:

To use the diagrams generated by this tool in your project, follow these steps:

  1. Include the Package:

From CTAN

\usepackage{mohelper}

Include this into your preamble. Note that this might not be the newest version. In case you depend on using a newer version go to 2.1.2.

  1. From Local

Download the package and include it into your project. To do so download the mohelper.sty file from

and paste the file into your project's root directory. Ensure you have the mohelper package included in your preamble:

\usepackage{mohelper}

If you put mohelper.sty into a subdirectory, you must specify its path. Therefore, have this example shown:

\usepackage{./lib/mohelper.sty}
  1. Configure your Diagram:

Open the Web Helper and set up your orbitals, energies, and labels.
