Dielectric behaviour of frozen DNA in solution. 
In this article, measurements are reported on ice and frozen DNA solutions between 100 Hz-10 MHz.  Pure ice is shown to exhibit single relaxation behaviour, which confirms previous work taken over a more restricted frequency range.  The frozen DNA solution displays double-dispersion behaviour.  One dispersion centred around 3 kHz is due to a defect mechanism while the other, centred around 2 MHz, may be attributed to counterion flow through the water immediately adjacent to the DNA molecule.
