In recent years, much effort has been devoted to the measurement and modelling of the threedimensional structure and the folding abilities of biologically-relevant molecules, including neurotransmitters [1] and building blocks of deoxyribonucleic acid (DNA) [2]. Previous studies have shown that one can differentiate between the conformers of the same molecule by combing quantum computations wit...

Observations from the Spitzer Space Telescope have drawn attention to spectroscopic structure longward of 15 mm that is associated with objects showing prominent unidentified infrared (UIR) bands in the mid-IR. If polycyclic aromatic hydrocarbons (PAHs) are indeed responsible for the UIR features, longer wavelength emission arising from out-of-plane PAH skeletal vibrations is required. Here we ...

The utility of infrared (IR) spectroscopy for the determination of strawberry ripeness has been successfully demonstrated. Transmission IR spectra were collected using dried liquid extracts from strawberry flesh. The overall IR feature provided fairly noticeable differences, and the ripeness stage was clearly identified using principal component analysis (PCA). Although all of the extracted com...

Vibrational spectroscopy has continued use as a powerful tool to characterize ionic liquids since the literature on room temperature molten salts experienced the rapid increase in number of publications in the 1990's. In the past years, infrared (IR) and Raman spectroscopies have provided insights on ionic interactions and the resulting liquid structure in ionic liquids. A large body of informa...

Interfacial oxidation and reduction of Prussian Blue (PB), KFe[Fe(CN)6]‚nH2O (n ≈ 10), powder were probed in situ with Fourier transform infrared attenuated total reflection (FT-IR/ATR) spectroscopy. The combination of electrochemistry in the absence of liquid electrolyte with internal reflectance FT-IR spectroscopy was accomplished using a simple two-electrode sandwich-type cell in which a cry...

Fourier transform infrared (FT-IR) spectroscopic imaging is an emerging technique that provides both chemically and spatially resolved information. The rich chemical content of data may be utilized for computer-aided determinations of structure and pathologic state (cancer diagnosis) in histological tissue sections for prostate cancer. FT-IR spectroscopic imaging of prostate tissue has shown th...

In this work facile sol-gel (pechni) method has been successfully established to synthesize Zn4B6O13 nanocrystals which have cubic crystals with lattice parameter: a =7.48 A. The structure and morphology of the obtained material were studied by X-ray diffraction (XRD), Infrared spectra (IR), scanning electron microscopy (SEM) and photoluminescence analysis. The experimental results show a band ...

A B S T R ACT : Infrared (IR) spectra of well-ordered kaolinites generally show four OH-stretching frequencies, near 3697, 3670, 3652 and 3620 cm i. Raman spectra of the same kaolinites mostly show an additional band near 3686 cm-~, which, in the coarsely crystalline Keokuk kaolinite, largely replaces the 3695 cm-I band. It is shown that the 3686 cm ~ band can be ascribed to a transverse optica...

m 0 7 r m a d s a t p f t u 4,4*-Diphenyltetrathiafulvalene (DPTTF) capped gold nanoarticles of 3to 5-nm diameter have been prepared and their hermal stability has been investigated by variable temperature T–IR spectroscopy. The DPTTF molecules at the cluster surface ndergo charge-transfer complexation with C60 to form Au/ PTTF.C60. Direct evidence of complexation is observed in the -ray photoe...

We present near-and mid-infrared images of the young stellar object N 160A-IR in the Large Magel-lanic Cloud (LMC). For the rst time, the YSO is seen in the NIR as a compact point source in the northwestern part of the H ii region N 160A. Furthermore, we present ISO-SWS spectra pointed on the YSO. The spectra cover the full wavelength range of SWS on board of ISO (2.5-45 m) where most of the du...
