Notes:
A transient electric birefringence computerized spectrometer inducing Kerr effect in anisotropically polarizable solutions such as DNA is described. Rectangular unipolar or bipolar pulses up to 400 V (I〈10 A) can be applied to solutions with relatively high conductivity. The software developed for recording the signal in a PC/AT computer, interpreting the shape of the signals and plotting the experimental and theoretical curves, is also described. The software is written in turbo Pascal 5.0, except for the Labcard driver, which is in 80286 assembly language. The performances of the apparatus have been checked on various DNA solutions.
