Computer Analyses of Complex Kinetics Containing Equilibrium Processes. Example of Application for Unusual Atropisomerization of a Tetraphenylporphyrin Derivative

Kinetic behavior of atropisomerization of tetraphenylporphyrin derivative containing equilibrium processes of dimer formation were analyzed directly by a non-linear least square optimization method which uses numerical integration of kinetic differential equations. Analyses clearly indicate a kinetic model determined with one rate and two equilibrium constants as the most plausible mechanism.
