Abstract
Two different multidimensional pulsed field gradient sequences are compared which have the purpose of correlating spin displacements in different time intervals with each other. The simplest possible sequence, three-pulse SER PENT, measures displacements in two interleaved time intervals, while in VE XSY, consisting of two independent pairs of gradient pulses separated by a mixing time, displacements during the two encoding intervals are compared t o each other. The formalism for both sequences is discussed in q space and in displacement space and common features as well as differences between th e two types of experiments are highlighted, employing the particular case o f the concurrent VEXSY scheme which allows treatment according to both form alisms.
