摘要：

Surface enhanced Raman scattering (SERS) of maleimide adsorbed on colloidal silver, colloidal gold and Ag island films has been observed. A strong chemisorption of the maleimide molecule to the metal surface was evident from the observation of the corresponding metal-molecule stretching vibration. The normal coordinate analysis (NCA) of the metal complex was carried out using the force field of the isolated molecule and a Ag-N force constant. The NCA of the in-plane modes included two possible configurations of the metal-adsorbate complex, allowing an interpretation of SERS spectra obtained with fresh and aged colloids and an approximate description of the surface sensitive vibrational fundamentals.
