S-State Program

This program simulates the water-splitting mechanism of PSII (the S-state mechanism). The results are the amplitudes of oxygen yields under flashing light. Two models are available: the Kok model extended to a 6-step mechanism, and Dr. Meunier's photoactivation model (Photosynthesis Research 47 (1996):61-76).

This program will only run on Macintosh computers that can work in the Classic environment. The program will only run on Macintosh computers with OS9x or older operating systems. This includes the Classic environment included with many OS10x machines. It is provided as a binhexed self-extracting archive. The download should open automatically with Stuffit Expander.
