Contracted GTF basis sets applied to the theoretical interpretation of the Raman spectrum of hexaaquachromium(III) ion
(2003-04-25)
Contracted GTF basis sets designed with aid of the Generator Coordinate Hartree-Fock (GCHF) method for H(2S), O2-(1S), and Cr3+(4F) atomic species are applied to perform theoretical interpretation of the Raman spectrum of ...

Surface-enhanced raman spectra of phthalimide. Interpretation of the SERS spectra of the surface complex formed on silver islands and colloids
(American Chemical Society, 2000)
The surface-enhanced Raman scattering (SERS) spectra for phthalimide (PIMH) vacuum evaporated, cast onto silver island films, and from colloidal silver are clearly identified with the formation of a phthalimide-silver ...
A quantum chemical guided interpretation of the infrared and Raman spectra of trimethylsilyl trifluoromethanesulfonate, CF3SO2OSI(CH3)3
(Elsevier Science, 2000-10)
The optimized structure and the wavenumbers of the normal modes of vibration were calculated for CF3SO2OSi(CH3)3 using density functional theory (DFT) methods, with a B3LYP functional and the 6-31G(**) basis set. The ...
Identification of species formed after pyridine adsorption on iron, cobalt, nickel and silver electrodes by SERS and theoretical calculations
(JOHN WILEY & SONS LTD, 2009)
The adsorption of pyridine (py) on Fe, Co, Ni and Ag electrodes was studied using surface-enhanced Raman scattering (SERS) to gain insight into the nature of the adsorbed species. The wavenumber values and relative intensities ...
Surface-enhanced Raman scattering study of L-tryptophan
(2009)
Surface-enhanced Raman scattering (SERS) spectra of tryptophan (Trp) were obtained. A unique SERS spectrum of Trp, corresponding to the most stable conformation and orientation on the metal surface, is observed after a ...
Experimental and theoretical conformational studies on diallyl sulfide
(Elsevier Science, 2019-04-15)
The conformational properties of diallyl sulfide (DAS), CH 2 [dbnd]CH–CH 2 –S–CH 2 –CH[dbnd]CH 2 , were studied with DFT methods. Eleven structures were found as potential energy minima with the B3LYP/6-31G(d,p) approximation. ...
