SURFACE-ENHANCED RAMAN SPECTROSCOPY STUDY ON ADSORPTION OF AN EMULSION STABILIZER(4-HYDROXY-6-METHYL-1,3,3A,7-TETRAAZAINDENE)ON A SILVER SURFACE |

| Abstract: | Adsorption of 4 hydroxy 6 methyl 1,3,3a,7 teraazaindene(TAI)on a silver surface was investigated by surface enhanced Raman spectroscopy(SERS).In the present system,TAI molecule is chemisorbed on the surface of silver electrode.The N atom of TAI plays the principal role of adsorption on the silver electrode.It is concluded that TAI molecule is adsorbed on the silver electrode by edged on mode.Although the number of ORC does not affect the frequencies of vibration,it obviously affects the intensities of SERS. |
