BKChem
From NMR Wiki
Overview:
BKChem is a free (as in free software :o) chemical drawing program. It was conceived and written by Beda Kosata.
BKChem is written in Python, an interpreted and very nice programming language. This implies some of the program features:
- platform independence - BKChem should run on any platform that Python does. - BKChem is developed on GNU/Linux. It was however successfully used under WinXP and MacOS X.
- performance - as Python is interpreted language you should not expect the performance of a native code compiled application (in present days a very cheap tradeoff for platform independence). However BKChem should be pretty usable on all modern systems.
