摘要: Surface-enhanced Raman scattering spectra of 1-phenyl-5-mercaptotetrazole (PMT) and the corresponding sodium salt adsorbed on silver sols were recorded in 3700–2800 1800–150 cm−1 regions. The SERS obtained both cases are same, therefore it can be deduced that PMT adsorbs sol ionized thiol form (PMTA). Moreover, similarity between normal complex (AgPMTA) is diagnostic chemisorption substance surface. data interpreted with help results DFT calculations PMTA AgPMTA. On basis description provided by potential energy distribution vibrational modes related to most enhanced bands spectra, interacts via lone pairs sulphur one nitrogen atoms. orientation tetrazole ring nearly edge-on respect metal surface, whereas molecular plane benzene inclined it.
