Monocamadas auto-organizadas da 2,2\':6\' ,2\" -terpiridina formadas sobre a superficie do eletrodo de Ag e Cu foram caracterizadas através da técnica SERS (Surface Enhanced Raman Spectroscopy) em experimentos ex situ e in situ. Foram estudadas alterações nas espécies adsorvidas em função da natureza das soluções-mãe e das soluções eletrolíticas utilizadas, tais como, solvente, pH da solução, ânion-suporte e a presença de outro adsorbato orgânico: a 2-mercaptopirimidina (mpy). Para estudar-se a adsorção da tpy foram obtidos padrões espectrais em que a molécula realiza diferentes interações com a vizinhança: no estado sólido, em solução, fundida e formando complexos com os íons CU2+ e Ag+. Também foram obtidos padrões para o ânion Cl04- co...
