摘要：

The infrared, Raman and surface-enhanced Raman scattering (SERS) spectra of 1,8-naphthalimide are presented. The material is studied as evaporated thin solid films, solid matrices in KBr pellets and in aqueous colloidal solutions. The vibrational information also includes FT Raman and far-infrared spectra. Characteristic normal modes are assigned using relative intensities and by comparison with naphthalene. Thin solid films have been evaporated onto a smooth silver metal film for reflection absorption FTIR spectroscopy (RAIRS) measurements, and onto a KBr disk for transmission FTIR. The molecular orientation of naphthalimide on surfaces is discussed using transmission, RAIRS and SERS data on colloidal silver. The wavelength dependence of SERS intensities for each irreducible representation are shown using three different laser lines for excitation.
