摘要：
The Raman, IR and SERS spectra of 2,4-diamino-6-phenyl-1,3,5-triazine (DPT) have been recorded. One protonated form of the DPT molecule was evidenced. The DPT molecule was found to adsorb on to a silver colloidal surface in either the neutral or the protonated form. Vibrational assignments are proposed for DPT and the DPT ion. Comparison of the Raman spectra of DPT and the DPT ion in solution with the SERS spectra results in an orientation with the triazinic skeletal DPT plane perpendicular on the Ag surface, The same orientation with more or less tilt was found for the adsorbed DPT ion.
