Proton-proton relaxation rate constants depend on the angle between the internuclear vector and the principal axis of rotation in symmetric top molecules. It is possible to determine to rotational correlation times of the equivalent ellipsoid for DNA fragments from a knowledge of the axial ratio and the cross-relaxation rate constant for the cytosine H6-H5 vectors. The cross-relaxation rate constants for the cytosine H6-H5 vectors have been measured in the 14-base-pair sequence dGCTGTTGACAATTA… CONTINUE READING
