Eine neue Methode zur Messung von Korrelationszeiten mit Hilfe von NMR-Impulsverfahren

Authors


Abstract

We demonstrate a new method for the determination of correlation times. This method is based on examining the temperature dependence of coherent pulse averaging effects. We derive formulas for the temperature dependence of the decay time T2eff of the transverse magnetization in the so called WHH and MW cases.

As application of this method we measured T2eff for OH-protons on a decationated Y-zeolite.
