Abstract

A transient electric birefringence computerized spectrometer inducing Kerr effect in anisotropically polarizable solutions as DNA has been used to investigate, at ambient temperature, the mechlorethamine-DNA interaction in presence and in absence of the WR-1065 radioprotector. The birefringence, and the time relaxation variations versus drug concentration are reported. An interpretation including DNA electrooptic properties is proposed.
