A constructive procedure for the preparation of arbitary two-spin evolutions via a tailored pulse-delay sequence of selective radio frequency fields was developed. The use of the procedure, based on factorization of an arbitary matrix, in controlling of a coupled two-spin system was examined. The frequency of any pulse in the sequence was one of the two Larmor frequencies and the Larmor frequency separation between the two spins were not large.
