Longitudinal magnetisation as a function of time in a two‐proton spin system undergoing dipolar cross‐relaxation. The two spins are placed 2.0 Å apart, the rotational correlation time is set to 1.0 ns, the temperature is set to 298 K, the chemical shift difference is 0.01 ppm; the magnet field is 14.1 Tesla. One of the spins is inverted at time zero. Left: no J‐coupling between the spins. Right: zero‐quantum beats resulting from a 3.0 Hz J‐coupling. The calculations are included into the standard example set supplied with Spinach
