In this study, the experiments for surface enhancement of silver mirror substrate were done, where we checked the characteristics of silver mirror substrate made by Tollen"s method. The surface enhancement of Bromothymol blue was analyzed by three kind of silver mirror substrates. The assignments of the vibrational bands shown in SERS spectra are given based on both literature and the semi-empirical calculations at the PM3 methods. Finally, we deduced that the adsorption orientation of bromothymol blue was little tilted flat to the silver mirror surfaces by using of the surface selection rules.
