Kinetic analysis of second order reactions using UV-VIS spectroscopy.
A new method was recently developed for the spectroscopic kinetic analysis of reactions with two linearly independent concentration variables. Firstly, the results of this theory applied to experimental data are represented. For this investigation, reactions of the mechanism type A + Bk (1)--> C + D and A + E uc-->|k(2)|F + G were chosen since both reaction steps can be studied separately. The evaluation of the reaction system consisting of both reaction steps gives satisfactory results when the methods of "formal integration" and "singular value decomposition" (SVD) are used. Absorption coefficients of absorbing species are not needed for the evaluation. Only time dependent spectroscopic measuring values and initial concentrations are used in the presented practical example.
