Reported the wavelength-scanned (WS) SERS spectra of 4-mercaptopyridine mols. (4-MPy) adsorbed on Au nanoparticles immobilized in a Langmuir Reverse Schaefer (L-RSh) film matrix of 5CB mols. The WS-SERS spectral profile exhibited an increment in the intensity of the enhanced Raman bands of 4-MPy with an increase in the wavelength of the excitation laser source. The rationale behind the exptl. observations was supported by the simulated extinction spectra and the enhancement factor measurements of the modeled systems using the T-matrix formalism. The SERS intensity fluctuations in the band located at 1000 cm-1 for the 4-MPy mol., as obtained from 3 different locations in the L-RSh film substrate, were analyzed. Depending on the spatial locations of the substrates, the intensity fluctuations of the abovementioned band exhibit both Poisson and Gaussian distributions but the maximum number of probe mols. that can reside in the scattering areas under study cannot exceed 16. Probably the origin of SERS from single/few mols. or from the ensemble-averaged system cannot be inferred from the statistical distributions of the Raman intensity fluctuations. The present exptl. observations also revealed the relation between the near-field plasmonic behaviors of the substrate with the corresponding far-field SERS spectra of the 4-MPy mol.
