Description by Patrick Giel (from Google Play)
Hueckel Molecular Orbital Theory - HMO

This App calculates molecules by Hueckel-approximate.
You can either input directly by the topology matrix or by the implemented own drawing system.

This values will be calculated by solving a determinant of the given matrix:
Eigenvalues, energy level diagram, bond ordering, charge ordering, net charge, free valences, atom-atom / bond-atom / bond-bond polarizability.

All values are graphically processed and can exported to PDF.

You can calculate physical quantum mechanical effects on your own Cellphone or Tablet.

Perfect for education in School and University.

Developed at the Technical University of Darmstadt - Theoretical Physical Chemistry / TU Darmstadt

★★★★☆ Pranshu Kumar Gupta (PKG) · Feb 12, 2022
It's really a good and handy app. However, I am not able to save my work as PDF. The procees gets killed once after giving the file name I click on save. I don't know why is this happening.
★★★★☆ Mounsif Abbes · Mar 21, 2021
Great app...but nickel determinant never show up... I only get Calculating determinants...forever 😔😔
★★★★★ Eduardo Hernández Requejo · Jul 8, 2020
This is a very useful app, I use it very frequently. Whether I'm trying to estimate most likely reactions or wich product configuration will be favored in a reaction, this app helps to do it in a very convenient way.
★★★★☆ Callie Smith · Nov 13, 2019
It does not have every atom, and it won't let me combine O and B. But it is a great app.
