摘要：

This article presents the synthesis of Au/Li nanoparticles through green synthesis approximation, using extract from Opuntia ficus indica (OH). The TEM images show the efficiency of this method for the synthesis of nanoparticles. The vibrational properties of Au/Li nanoparticles were analyzed through Raman spectroscopy. The results of the analysis show two vibrational bands around 93 cm(-1) and 242 cm(-1). Furthermore, the article presents a theoretical study of clusters Au(m)Li(k)in which obtained minimum energy structures were obtained and predicted the normal modes of vibration in the Raman spectrum of each one of the clusters AumLik. We observed a theoretical and experimental behavior in the optical and the vibrational properties.
