Multiple quantum (MQ) NMR dynamics in a system which was prepared initially in dipolar ordered state is investigated with analytical and numerical methods for linear open chains of nuclear spins 1/2 coupled by dipole-dipole interactions. We show that the phases of the signals of MQ coherences are shifted by p/2 with respect to the signals of the ordinary MQ NMR experiment. The sum of the intensities of MQ coherences of arbitrary opposite orders in this experiment is equal to zero. Many-spin correlations are created faster in the such experiments and can be used for investigations of many-spin dynamics of nuclear spins in solids.
