Prochazka et al. demonstrated the suitability of surface-enhanced resonance Raman scattering (SERRS) spectroscopy to monitor silver coordination of free base 5,10,15,20-tetrakis(l-methyl-4-pyridyl) porphyrin adsorbed on the Ag colloidal surface. The approach was based on factor analysis (FA) which allows the analysis of the time development of SERRS spectra in terms of varying content of particular porphyrin forms. Their SERRS spectra can be isolated even if none of them is present singularly in any SERRS spectmm. Depending on the chemical properties of the molecular systems, SERRS spectra of two different porphyrin metalated forms have been obtained Ag+ and Ag metalated. The latter form was found to be evoked by pre-treatment of the laser-ablated Ag colloids by the thiosulphate ions. The metalation kinetics obtained show a substantially slower metalation by Ag than that by Ag+ cations.
