Geometrical optimization and frequency calculations on [HRh(CO) 4 ] were carried out using density functional theory methods with the B3LYP, PBE and B3PW91 functionals in conjunction with the LanL2DZ and DGDZVP basis sets. The accuracy of each calculation was verified by comparing the predicted and the experimentally obtained deconvoluted mid-infrared experimental CO stretching frequencies...
The adsorption of biologically important Rhodamine 123 molecule on silver colloids has been investigated by Surface enhanced resonance Raman scattering (SERRS) spectroscopy. The SERRS spectra are compared with its FTIR spectrum and normal Raman spectrum (NRS) in solution. The optimized structural parameters and computed vibrational wavenumbers have been estimated from ab initio (Hatree–Fock) and density...
