Disk No: 938 Disk Title: Chemical Molecular Modeling PC-SIG Version: S1.4 Program Title: Chemical Author Version: 4.2 Author Registration: $20.00 Special Requirements: 640K RAM, and CGA or EGA. CHEMICAL is a molecular-modeling program for 3-D representations of chemical elements. Select atoms from the Periodic Table and the program retrieves the electron orbital information. The atoms can be bonded into molecules, and the molecules bonded with other molecules to make large chemical structures. The chemical is displayed as it is constructed, and when formed, can be rotated and viewed. The hybrid and ionize commands can be used to alter the orbitals before bonding. Read, write and view a chemical data file from the disk. CHEMICAL also has a help function and a tutorial. Included is CHEMVIEW (an EGA-only function), a companion program that shows three-dimensional animation of the models made with CHEMICAL.
