Hueckel Molecular Orbital Theory - HMO is a free, educational application that can calculate and plot the energy levels, eigenvalues, and eigenfunctions of all possible molecular structures. This allows you to study the structure of the molecule in detail and understand its properties and interactions with the environment. It is suitable for both students and researchers in physical chemistry and biochemistry.

HMO can be used as a teaching tool to help students and teachers understand and remember the basics of quantum mechanics. It is also a practical tool for calculating and plotting the spectra of a wide range of compounds. This is useful for studying the properties of different materials and the interaction of the components with each other.
