摘要：

The Na-23 relaxation in isotropic and anisotropic aqueous, salt-free DNA fragment (500 Angstrom) solutions is investigated. The temperature dependence of the coupling constants and correlation times are reported. Premelting effects occur in the isotropic phase, whereas this is not observed in the anisotropic solution. Slow dynamic processes in the frequency range 200-9000 Hz are absent in both phases.
