Download or read book Wavelength Standards in the Infrared written by K.N. Rao and published by Elsevier. This book was released on 2012-12-02 with total page 247 pages. Available in PDF, EPUB and Kindle. Book excerpt: Wavelength Standards in the Infrared is a compilation of wavelength standards suitable for use with high-resolution infrared spectrographs, including both emission and absorption standards. The book presents atomic line emission standards of argon, krypton, neon, and xenon. These atomic line emission standards are from the deliberations of Commission 14 of the International Astronomical Union, which is the recognized authority for such standards. The text also explains the techniques employed in determining spectral positions in the infrared. One of the techniques used includes the grating constant method of determining spectral positions which measures the angular rotation of the grating. Another technique used is the modern gratings and high resolution infrared spectra which has made it possible to obtain narrower spectral lines. Computers can expedite the processing of observed data. Fraley and Rao have developed a procedure for data, obtained using double-pen recorders. The technique involves using visible neon lines to produce a wave number scale on the infrared spectra that is to be measured. This book can prove valuable to researchers and scientists working in the field of molecular, nuclear or atomic physics.

Download or read book Chemometrics in Spectroscopy written by Howard Mark and published by Academic Press. This book was released on 2018-07-13 with total page 1090 pages. Available in PDF, EPUB and Kindle. Book excerpt: Chemometrics in Spectroscopy, Second Edition, provides the reader with the methodology crucial to apply chemometrics to real world data. It allows scientists using spectroscopic instruments to find explanations and solutions to their problems when they are confronted with unexpected and unexplained results. Unlike other books on these topics, it explains the root causes of the phenomena that lead to these results. While books on NIR spectroscopy sometimes cover basic chemometrics, they do not mention many of the advanced topics this book discusses. In addition, traditional chemometrics books do not cover spectroscopy to the point of understanding the basis for the underlying phenomena. The second edition has been expanded with 50% more content covering advances in the field that have occurred in the last 10 years, including calibration transfer, units of measure in spectroscopy, principal components, clinical data reporting, classical least squares, regression models, spectral transfer, and more. Written in the column format of the authors’ online magazine Presents topical and important chapters for those involved in analysis work, both research and routine Focuses on practical issues in the implementation of chemometrics for NIR Spectroscopy Includes a companion website with 350 additional color figures that illustrate CLS concepts

Available in PDF, EPUB and Kindle. Book excerpt: A convenient single volume handbook featuring the most important topics in spectroscopy This valuable handbook is based on topics presented in the CRC Handbook of Spectroscopy, Volumes I and II, published in 1974, and Volume III, published in 1981. The information has been condensed (by the original contributor, when possible) so that only the most important information from the original three volumes has been retained and updated. The topics covered include ESCA flame photometry; atomic absorption and emission spectroscopy, including plasma emission; infrared spectroscopy; Raman spectroscopy; ultraviolet absorption spectroscopy; electron spin resonance, X-ray spectroscopy, mass photoelectric absorption coefficients, appearance potential spectroscopy, thermal neutron cross sections and resonance integrals for activation analysis, tables of experimental values of X-ray fluorescence and Coster-Kronig yields for the K-, L-, and M-shells. Other topics include 14 MeV neutron activation cross sections; wavelength standards in visible, ultraviolet, and near-infrared spectroscopy; electron affinities, wavelength-dependent and electronic system oscillator strengths for free diatomic molecules of astrophysical importance; electron spin resonance applicaton to the study of minerals and glasses; experimental lifetimes, Franck-Condon factors; and vibrational and rotational oscillator strengths. The concise format and wealth of information ensures that no spectroscopist will want to be without the updated and revised Practical Handbook of Spectroscopy.
