Comparison of SERRS and RRS excitation profiles of [Fe(tpy)2]2 (tpy = 2,2':6',2''-terpyridine) supported by DFT calculations: effect of the electrostatic bonding to chloride-modified Ag nanoparticles on its vibrational and electronic structure

Popis výsledku v původním jazyce

Nonresonance (or normal) Raman scattering (NRS), resonance Raman scattering (RRS), surface-enhanced Raman scattering (SERS), and surface-enhanced RRS (SERRS) spectra of [Fe(tpy)2]2+ complex dication (tpy=2,2':6',2''-terpyridine) are reported. The comparison of RRS/NRS and SERRS/SERS excitation profiles of [Fe(tpy)2]2+ spectral bands in the range of 445-780nm is supported by density functional theory (DFT) calcu lations, Raman depolarization measurements, comparisonof the solid [Fe(tpy)2](SO4)2 and solution RRS spectra, and characterization of the Ag nanoparticle (NP) hydrosol/[Fe(tpy)2]2+ SERS/SERRS active system by surface plasmo n extinction spectrum and transmission electron microscopy image of the fractal aggregates (D=1.82). By DFT calculations, both the Raman active modes and the electronic states of the complex have been assigned to the symmetry species of the D2d point group. It has been demonstrated that upon the electrostatic bonding of the complex dication to the chloride-mo
