On Data Processing, Evaluation and Precision of Relaxation Measurements

Abstract

Chemical relaxation techniques have been introduced by Eigen and coworkers about twenty years ago. Since that time, the precision of the techniques has been improved considerably and especially the signal-to-noise ratio of the measurements has been enlarged. Due to the higher precision it may turn out that there are two relaxation effects in a system studied, where only a single one was detected with less accurate equipment, or that there is a strong disturbance by an instrumental effect missed in former measurements. To discriminate between a single or a multiple exponential, to eliminate disturbances, and to increase the accuracy of the results also the techniques of evaluating the measurements and of data processing have been developed further.
