Derivation of Rydberg Constant: a demo program from the Atomic Orbitals CD . An interactive tutorial showing you a step-by-step the derivation of Rydberg constant; with hypertext and animation. (screen shot 96k)
• For Mac: Click here to download the binhexed archive rydberg.HQX (1.1M).
• For Windows: Click here to download the pkzip archive rydberg.ZIP (887K).

Electron Distribution of 2s orbital: a demo program from the Atomic Orbitals CD . You can cut a slicing plane (as XY, YZ, and XZ planes) through the 2s orbital to reveal its electron distribution. The 3D models and images are scientifically accurate. 2s orbital has one node. You will find the node easily in this program. (screen shot 38k)
