Introduction

In the realm of quantum chemistry, understanding molecular orbitals (MOs) is crucial for grasping the behavior of molecules. However, visualizing MOs can be a daunting task, especially when relying on traditional three-dimensional electron density plots. These plots often require significant computational resources and may not always provide a clear insight into the nodal structure of MOs. This is where MOPlot comes into play, offering a revolutionary approach to visualizing MOs, geometries, and normal vibrations in a 2D projected format.

What is MOPlot?

MOPlot is a powerful tool designed to fill the gap left by traditional graphic tools in quantum chemistry software. By producing 2D projected images from the output of standard quantum chemical programs, MOPlot provides an intuitive and interactive way to visualize molecular structures, MOs, and normal vibrations. This innovative approach enables researchers to gain a deeper understanding of molecular behavior and properties.
