The evolution of N spins is simulated in a reduced Liouville space X which excludes coherences involving more than k spins, where k << N is chosen to minimize the dimension of X without introducing unacceptable error. For polarization transfer within a spinning lattice of protons, comparison with exact simulations shows that k = 4 allows accurate simulation of the experimentally relevant powder-averaged curves. A simulation of polarization transfer among 144 protons is presented. (C) 2009 Elsevier B. V. All rights reserved.text::journal::journal article::research article
