Unlike standard molecular visualization tools that merely display ball-and-stick models, AIMAll delves into the topology of the electron density. It reads wavefunction data from quantum chemistry packages (like Gaussian, GAMESS, and ORCA) and allows users to visualize the "reality" of chemical bonds. AIMAll Professional Free Download
