Thermal motions in nucleic acids produce random, fluctuating magnetic fields that may influence the relaxation of nuclei on the nucleic acid which are interacting with the fluctuating fields. The strength of the interaction as well as the nature of and rate of the fluctuations will govern the nuclear spin relaxation. The strength of the interaction can be expressed in terms of a Hamiltonian. Molecular motions will cause the orientation of the Hamil-... [Pg.350]
