When I was first approached to edit a volume on Femtosecond Laser Spectroscopy in 2000, I did not anticipate that the field was about to explode, with the announcement of a series of remarkable new developments and advances. This volume describes these recent developments in eleven chapters written by leading international researchers in the field. It includes sections on: Femtosecond optical frequency combs, which are currently revolutionising ultrahigh precision spectroscopy and optical frequency metrology;...

Nuclear magnetic resonance (NMR) spectroscopy has made quantum leaps in the last decade, becoming a staple tool in such divergent fields as chemistry, physics, materials science, biology, and medicine. That is why it is essential that scientists working in these areas be fully conversant with current NMR theory and practice.

Tungsten oxide film was deposited on ITO-coated glass by using RF magnetron sputtering method from WO3 ceramic target. Thin film preparation – process took place in Ar + O2 plasma. The dependence of tungsten oxide film structure on experiment conditions was investigated by X-ray diffraction (XRD) Raman spectroscopy. In this paper, we considered that the thickness of ITO layers about 150nm to 350nm clearly effects on the Raman and XRD spectrograms of WO3 films.

NMR spectroscopy is a powerful tool for studying the structure, function and dynamics of biological macromolecules. However, non-spectroscopists often find NMR theory daunting and data interpretation nontrivial. As the first of two back-to-back reviews on NMR spectroscopy aimed at non-spectroscopists

A new functionalized conducting poly(5-hydroxy-1,4-naphthoquinone-co-5-hydroxy-3-acetic acid-1,4-naphthoquinone) with electroactive quinone group was studied by in situ Raman spectroscopy. The Raman results confirmed a good reversible transformation between two structures: quinoid and hydroquinoid ones during reduction-oxidation processes.

The conducting polymer poly(5-hydroxy-1,4-naphthoquinone-co-5-hydroxy-3-acetic acid-1,4- naphthoquinone) with electroactive quinone group was investigated by Electrochemical Impedance Spectroscopy (EIS) in aqueous medium. The evaluations of parameters of equivalent circuit in term of applied potential were considered. The simulated EIS data presented a good agreement with the results obtained by other electrochemical methods.

In this report, we use a sum-frequency generation vibrational spectroscopy to measure SFG spectra from 1-Butanol monolayers on pure water and halide saline solution interfaces. These spectra indicate that halide anions have different effects on the structure of 1-Butanol monolayer/water interfaces. The obtained SFG spectra suggest that the I¯ anions mostly disturb the interfacial structure due to their largest surface propensity among those investigated.

In this report, we studied the effect of halide salt concentration on Arachidic Acid (AA) Langmuir monolayers formed on salt solutions, such as NaCl, NaI, NaF by using a SumFrequency Generation Vibrational Spectroscopy. In the SFG spectra, we observed the peak intensities of CH3FR and CH3SS vibrational modes decreased when increasing the salt concentration. This observation indicates that the structure of the AA monolayer was disordered by the interaction of the dissolved ions with the carboxyl head groups of the monolayer.
