Abstract

Surface-enhanced resonance Raman scattering spectra were measured for meso-tetraphenylporphine (TPP) and its Ag(II), Mg and Zn complexes in a layered structure, having an Ag/sample/CaF 2-roughened-substrate configuration. The structural data of SERS-active species give information about and Ag incorporation and/or a metal-exchange reaction of TPP and MgTPP during the Ag deposition process.
