Methodical Aspects of 2D NMR Correlation Spectroscopy under Conditions of Ultra High Pulsed Field Gradients

1. Introduction Multidimensional NMR methods have become an important tool in the 1970s. In the past years a new set of experiments has developed whose postprocessing is based on a multidimensional inverse Laplace transformation rather than a Fourier transformation which provides the capabilities to find correlations between various parameters such as diffusion coefficients D and NMR relaxation times T 1 and T 2 [1,2]. The aim of the present work is to implement these techniques to our spectrometers in order to combine the concept of ultra high pulsed field gradients of up to 35 T/m [3] with modern 2D NMR correlation experiments.
