Hi all We know that the presence of paramagnetic materials in the sample, if only in traces, is leading to very broad and unresolved signals with a bad signal to noise ratio. The reason is that they are relaxing the nuclei of the sample very fast and the FID has no time to evolve. Do you have suggestion for obtain a better spectrum in case of paramagnetic sample ? Thank you
