%X Silver and copper foils for surface enhanced Raman study were prepared by chemical etching method with HNO3. These foils exhibit better enhancement factor and higher thermal stability than the vacuum deposited silver island film. The surface geometry of poly (4-vinylpyridine) and polybenzimidazole has been determined by observing relative intensity change of the out-of-plane and in-plane ring vibration bands in their SERS spectra. The two polymers show two orientations in which the rings are "lying down" or "standing up" from the surface resulted from different sample methods.
