Abstract
The evolution operator for an arbitrary spin system in an arbitrary time-varying magnetic field is disentangled into the rotation operator; consequently, the time-ordering problem is shifted into solving the Euler geometric equations. Some realistic transformations are proposed in order to find their analytic solutions. The probabilities and phases characterizing state transitions are also analyzed.
