Abstract
Many papers and books show graphs of hydrogen orbitals using plots of R(r) vs. r, Q(q) vs. q, and F(f) vs. f. These graphs may be made by anyone with access to Excel. Contour maps of isodensity is another way of showing orbitals, especially for molecules. Math software packages like MATHCAD and MAPLE enable students to make rotatable three-dimensional (3d) graphs of the density per solid angle | Q(q)|2 |F(f)|2 of hydrogen-like atomic orbitals as a function of q and f ( see reference 1). The work herein shows how to produce rotatable 3d density plots of orbitals which also include radial dependence |R(r)| 2.
