SYNOPSIS

The complex dielectric response of calf thymus DNA in aqueous saline solutions has been measured from 1 MHz to 1 GHz. The results are presented in terms of the relaxation of the incremental contributions to the permittivity and conductivity from the condensed counterions surrounding the DNA molecules. Measurements of the low-frequency conductivity of the samples also lends support to the condensed counterion int,erpretation.

The dielectric properties of aqueous solutions of DNA were measured at frequencies ranging from 0.1 to 12 GHz. The results are analyzed using the Maxwell mixture theory and yield a value for the hydration of the DNA of about 0.4 g/g, which is in the range ohserved in other investigations. No evidenc

## Abstract Equations are derived which account for the effect of an applied electric field on the fluctuation of protons associated with a macromolecule. The contribution of this proton polarization to the complex permittivity of the macromolecules is evaluated in terms of its effect on both the d
