Abstract
A new software package, ’KINFITSIM’, for fitting and simulating kinetic data is presented. The main goals of the KINFITSIM package are to obtain the best-fit parameters-rate constants, amplitudes and others-to a user specified chemical mechanism, plots of the calculated and experimental absorbance versus time, and a report to the user with the results. The KINFITSIM package can be used in either chemical research or for educational purposes.
