Abstract
NMR transverse relaxation process under intermolecular dipolar interactions of order n was studied quantitatively. An analytical expression was derived using a combined demagnetizing field and the product operation formalism. The theoretical expression predicts that the apparent transverse relaxation time T 2, n = T 2/| n| for | n|>1 during the evolution period, where T 2 is the conventional transverse relaxation time. A modification for the CRAZED pulse sequence which eliminates the influence of radiation damping was proposed for measuring T 2, n . All experimental measurements from spectroscopic or imaging measurements at several different magnetic fields are in excellent agreement with the theoretical prediction.
