After informed by a netter, I want to make clearer on my earlier post. Yes, we want the time constants in the sum of exponentials, it is basically "relaxation spectrum" analysis as analogous to FFT in "frequency spectrum". We tried to use nonlinear fit of multiple exponentials to fit our data, the results were not very good. So we thought about the Laplace Transform. As I was informed, people studying NMR relaxation prcesses already developed certain technique for the analysis. Is it available from any ftp site? Is there a FLT as to FFT? Thanks in advance for helps. -- Fang Zhong 1-919-660-2524 Duke University Dept. of Physics fang@phy.duke.edu Durham, N.C. 27706
