Abstract
The Na-23 relaxation in isotropic and anisotropic aqueous, salt-free D NA fragment (500 Angstrom) solutions is investigated. The temperature dependence of the coupling constants and correlation times are reporte d. Premelting effects occur in the isotropic phase, whereas this is no t observed in the anisotropic solution. Slow dynamic processes in the frequency range 200-9000 Hz are absent in both phases.
