With the purpose to reveal consistency between multiple quantum (MQ)coherences and entanglement, we investigate numerically the dynamics of thesephenomena in one-dimensional linear chains and ring of nuclear spins 1/2coupled by dipole dipole interactions. As opposed to the calculation of the MQcoherence intensity based on the density matrix describing the spin system as awhole, we consider the "differentiated" intensity related only to the chosenspin pair based on the reduced density matrix. It is shown that theentanglement and the MQ coherence have similar dynamics only for nearestneighbors while we did not obtained any consistency for remote spins.
