Notes:
The influence of high electrostatic fields on Raman scattering has been studied. For fields approaching 108 V m-1 in polymers a contribution to the Raman intensity due to the non-linearity of the Raman polarizability could be demonstrated. These results are in agreement with theoretical considerations. The band position does not change within the achieved resolution of 0.1 cm-1 for fields up to 1.7 × 108 V m-1, as also expected from theoretical estimates. With pulsed fields of duration 〈 1 μs, field strengths exceeding the static breakdown strength could be applied. In this case, however, a very complex pre-breakdown behaviour was observed, influencing the Raman scattering in a manner not yet understood.
