## Abstract Real and imaganiry parts of complex dielectric constant of dilute solutions of DNA in 10^β3^__M__ NaCl with molecular weight ranging from 0.4 Γ 10^6^ to 4 Γ 10^6^ were measured at frequencies from 0.2 Hz to 30 kHz. Dielectric increments ΞΞ΅ were obtained from ColeβCole plots and relaxati

## Abstract A conductivity dispersion has been measured at very low frequencies (VLF) on several concentrated DNA solutions. By measuring simultaneously their electric birefringence decay, it is shown that the dielectric relaxation (which is related to the conductivity dispersion) is due to the mol
The dieleclric relaxation of DNA solutions has been investigated with and wilhout extraneous ions covering a wide frequency range. The effect of monovalent ions such m Na, K, and Li w well as divalent ions such as Mg, Ca, and Hg have been included in the study. These ions are found to have a profoun
