Abstract
We report here the first realization of time-resolved electro-optic Raman scattering in a liquid medium. Using the characteristic signal from a Raman active band, we show that an applied pulsed electric field induces a macroscopic particle reorientation which may be followed by the transient changes induced in the Raman signal. We have chosen a liquid-crystal material as the medium because this allows us to compare the static and dynamic response with other conventional techniques. This comparison indicates the foundation of a new method for characterizing orientational processes, and the dynamics thereof, at the local molecular structure level. The method does not require the use of perturbing dye or spin probes.
