Site-selective deposition of aerosol Pd nanoparticles on a substrate was employed to fabricate nanoscale Ag dots and rings through a subsequent electroless deposition. The fabricated nanoscale dot and ring arrays respectively showed properties in surface-enhanced Raman (SER, with a 1.8 × 10(5) enhancement factor) and Fourier transform near infrared (FT-NIR, at 6153 cm(-1) absorption band) spectra.

In the present work, structural and spectroscopic investigations were carried out on a borreverine derivative. Borreverine is a class of alkaloid as well a natural antimalarial drug extracted from Borreria verticillata. With the aim of finding possible conformers, a detailed conformational analysis of a borreverine derivative was conducted utilizing density functional theory employing the B3LYP...

Toluene, also known as methylbenzene or phenylmethane, is a clear, waterinsoluble liquid with the typical smell of paint thinners, redolent of the sweet smell of the related compound benzene. It is an aromatic hydrocarbon that is widely used as an industrial feedstock and as a solvent. Like other solvents, toluene is also used as an inhalant drug for its intoxicating properties [1,2]. Toluene r...

There is no doubt that the contribution of microbially mediated bioprocesses toward maintenance of life on earth is vital. However, understanding these microbes in situ is currently a bottleneck, as most methods require culturing these microorganisms to suitable biomass levels so that their phenotype can be measured. The development of new culture-independent strategies such as stable isotope p...

In this work, the molecular conformation and vibrational analysis of 4-Amino-2, 2, 6, 6-tetramethylpiperidine (abbreviated as ATMP) were presented for the ground state using experimental techniques (FT-IR and FT-Raman) and the spectra were interpreted with the aid of normal coordinate analysis based on ab initio Hartree−Fock (HF) and density functional theory (DFT/B3LYP) methods with 6-311+G (d...

Combined experimental and theoretical studies on molecular and vibrational structure of 2-nitrobenzaldehyde and 4-nitrobenzaldehydes are reported. The Fourier transform infrared and Fourier transform Raman spectra of 2NB and 4NB has been recorded in the solid phase. The optimized geometry has been calculated by HF and B3LYP methods with 6-311++G(d,p) basis set. The harmonic vibrational frequenc...

The FT-IR and FT-Raman vibrational spectra of selegiline were recorded. The optimized geometry and wavenumbers in the ground state were calculated using density functional (B3LYP) method with standard 6-31G(d,p) basis set. The computed B3LYP/6-31G(d,p) results show the best agreement with the experimental values over the other methods. Natural bond orbital analysis of selegiline is also carried...

In this work, the FT-IR and FT-Raman spectra of 1-naphthaleneacetic acid methyl ester (abbreviated as 1-NAAME, C(10)H(7)CH(2)CO(2)CH(3)) have been recorded in the region 3600-10 cm(-1). The optimum molecular geometry, normal mode wavenumbers, infrared and Raman intensities, Raman scattering activities, corresponding vibrational assignments, Mullikan atomic charges and other thermo-dynamical par...

The effects of laser etching, decontamination, and storage treatments on dentin components were studied using Fourier transform (FT)-Raman spectroscopy. Thirty bovine incisors were prepared to expose the dentin surface and then divided in two main groups based upon the decontamination process and storage procedure: autoclaved (group A, n=15) or stored in thymol aqueous solution (group B, n=15)....
