Scanning-Fit Analysis of fs-Spectroscopic Data

Received27 Mar 2000

Abstract

The scanning-fit method was developed for the global data analysis of pump-probe data. This method is useful in cases when pulse durations are adjusted to be short compared with nuclear dynamics and long compared with the dephasing timescales. Then multiexponential functions can be used to describe the mono molecular relaxation processes and the scanning-fit method increases the accuracy of the calculated time constants, yields detailed information about their ranges of confidence and their dependency from each other. In this paper we describe the method in detail and demonstrate its application to simulated data. Additionally, we report about the results which were obtained from scanning-fit analysis in case of the photoisomerization of pinacyanol and the light induced processes in phycocyanobilin.
