✦ Synopsis

The study of the surface enhanced Raman spectroscopy (SERS) excitation profiles of 1,5-dimethylcytosine on metal colloids allows a more detailed determination of the behavior of the functional groups of this molecule in the adsorption process on the metal supports. Silver has shown its effectiveness and selectivity as a support for this technique from the point of view of its stability and capability to enhance the Raman signal coming from the adsorbate. The results are discussed in terms of the two well-known theories proposed up to now to explain the SERS phenomenon: electromagnetic and chemical (or charge transfer) models.

In SERS-active systems, when a free base porphyrin is adsorbed at a roughened metal surface, the metal ion may be incorporated into the porphyrin core. We have investigated the metalation kinetics of 5,10,15,20-tetrakis(1methyl-4-pyridyl)porphyrin (TMPyP), reÑected in the time evolution of its SERRS
