Flow method with integrating observation for very fast irreversible reactions

The continuous flow method, with observation along the concentration profile in the direction of flow, has previously been used to measure the rate constants of very rapid irreversible reactions up to 107 1 mol−1 sec−1. Improvements in the cell design and in the monitoring facilities now permit the study of reactions with rate constants greater than 109 1 mol−1 sec−1. The rate constants of eight electron transfer reactions of transition metal complexes are reported in this article.
