Abstract
It is difficult for us to imagine the three-dimensional appearance of atomic orbitals from the formulae of the solution of Schroedinger wave equation. In this paper, we would like to report the visualization of three-dimensional contour surfaces of a series of hydrogen atomic orbital functions using a software called AVS (Application Visualization System) on an EGWS (Engineering Graphic Workstation), IRIS INDIGO XS24 or TITAN 3000. From these drawings, the relationship between the number of lobes and nodes of atomic orbitals was derived.
