Vector data medium in an inhomogeneously broadened two-level NMR-system

A dynamical approach in combination with the proper geometric Clifford algebra is proposed to describe information flows formed during resonance application of rf magnetic field pulses to an inhomogeneously broadened two-level nuclear spin system. It permits one to introduce a notion of vector data medium and to follow spin system evolution in four different ways, which are connected through the formalism of Cayle-Klein parameters. The notion of coherence is generalized to include differences in space orientations and resonance frequencies for elements of the vector data medium. It is shown that information about pulse parameters of an excitation sequence is written in a spin system with manifold redundancy and by no means is always available for reading. The approach allows one to calculate all information flows which are formed in an arbitrary inhomogeneously broadened two-level system under conditions of any multipulsed experiment as well as necessary and sufficient conditions for their reading for a given way of detection.
