<SUP>31</SUP>p NMR spectra were obtained from the A-form and B-form of DNA fibers as well as from poly (dA-dT)·poly (dA-dT) has two distinct geometries. In contrast, the A-form poly (dA-dT)·poly (dA-dT) has a single conformation. The orientation of the phosphodiester group relative to the helical axis was determined on the A-form and compared with that observed by other methods. The conclusions obtained from DNA in the fibrous state were fully consistent with those from DNA in solution.
