Infrared and Raman Spectroscopy: Principles and Spectral InterpretationElsevier, 13 juil. 2011 - 230 pages Infrared and Raman Spectroscopy: Principles and Spectral Interpretation explains the background, core principles and tests the readers understanding of the important techniques of Infrared and Raman Spectroscopy. These techniques are used by chemists, environmental scientists, forensic scientists etc to identify unknown chemicals. In the case of an organic chemist these tools are part of an armory of techniques that enable them to conclusively prove what compound they have made, which is essential for those being used in medical applications. The book reviews basic principles, instrumentation, sampling methods, quantitative analysis, origin of group frequencies and qualitative interpretation using generalized Infrared (IR) and Raman spectra. An extensive use of graphics is used to describe the basic principles of vibrational spectroscopy and the origins of group frequencies, with over 100 fully interpreted FT-IR and FT-Raman spectra included and indexed to the relevant qualitative interpretation chapter. A final chapter with forty four unknown spectra and with a corresponding answer key is included to test the readers understanding. Tables of frequencies (peaks) for both infrared and Raman spectra are provided at key points in the book and will act as a useful reference resource for those involve interpreting spectra. This book provides a solid introduction to vibrational spectroscopy with an emphasis placed upon developing critical interpretation skills. Ideal for those using and analyzing IR and Raman spectra in their laboratories as well as those using the techniques in the field.

Principles and Spectral Interpretation Peter Larkin. Raman scattering is far less probable than Rayleigh scattering with an observed intensity that is ca. 10À6 that of the incident light for strong Raman scattering. This scattered photon ...
... Raman spectra have a very strong center-burst and rapidly damped intensity in the wings of the interferogram. It is necessary to precisely know the optical path differences in the interferometer and this is accomplished using a ...
... band shapes as a result of anomalous dispersion of the refractive index in an absorption band (Christiansen effect). False spectra due to non-uniform sample thickness are characterized by broadening of the bandshape of the strong bands ...
... bands will be increased relative to intense bands and the strong intensity bands will have broader, rounder peak shapes. A KubelkaeMunk conversion available in most FT-IR software packages can compensate for some of these effects. 2.5 ...
