  • 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;...

  • 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.

  • uclear magnetic resonance spectroscopy can now be used to investigate the biochemical energetics of human tissues and organs noninvasively. The method already has increased our understanding of some muscle diseases, has provided information from muscle metabolism about whole-body functions, control, and hormonal status, has helped in the elucidation of hitherto unrecognized causes of disease, and yielded new ideas about the control of bioenergetics in vivo. Studies on the biochemistry of human brain, liver, heart, and kidney are just beginning.

  • Modern Spectroscopy has been written to fulfil a need for an up-to-date text on spectroscopy. It is aimed primarily at a typical undergraduate audience in chemistry, chemical physics, or physics in the United Kingdom and at undergraduate and graduate student audiences elsewhere. Spectroscopy covers a very wide area which has been widened further since the mid- 1960s by the development of lasers and such techniques as photoelectron spectroscopy and other closely related spectroscopies.
