چکیده مقاله:
The increasing importance of noble metal clusters has made their structure determination one of the hot topics of the day. Vibrational spectroscopy is one of the classically efficient ways for this goal. In this work we have used a particular kind of photon-dissociation spectroscopy called “the messenger technique” alongside resonance Raman scattering to increase the efficiency and sensitivity of the structure determination process. We have used three closed-shell silver clusters Ag4, 6, 8 interacted with ligand N2 for our research. The results show great improvements compared to other spectroscopic methods indicating that this method could be a great replacement in cases that IR spectroscopy fails to give accurate results.
