Abstract

The influence of static electric field of about 4.9 kV/cm on optically trapped polystyrene bead has been studied using micro-Raman spectroscopy. This experimental method could explore the response of electronic polarizability of molecules to the static electric field by measuring the Raman intensity. It is observed that, the atomic electrons in polystyrene will polarize to the extent that they induce a Raman intensity enhancements by a factor ranging from 0.004 to 0.64 for various spectral bands of polystyrene when exposed to the electric field from ~4.90 to 4.96 kV/cm.
