Practical Guide to Interpretive Near-Infrared Spectroscopy
10/26/2007
Offers more than 300 figures representing all the major functional groups and their NIR frequency ranges Contains over 120 pages of tables and charts illustrating overlapping spectra Covers NIR spectra for organic compounds including alkanes, carboxylic acids, amines, dienes, alkynes, heterocyclic compounds, amino acids, and aldehydes Provides comprehensive appendices with spectra-structure correlations, example spectra, and other useful data for interpreting NIR spectra
Containing focused, comprehensive coverage,Practical Guide to Interpretive Near-Infrared Spectroscopygives you the tools necessary to interpret NIR spectra. The authors present extensive tables, charts, and figures with NIR absorption band assignments and structural information for a broad range of functional groups, organic compounds, and polymers. They include visual spectral representation of all major compound functional groupings and NIR frequency ranges. Organized by functional group type and chemical structure, based on standard compound classification, the chapters are easy to follow and understand. The use of Molecular Formula and CAS Number indexing prevents the confusion that can occur when using only common chemical names to identify compounds.
Interpretive spectroscopy provides a basis for the establishment of cause-and-effect relationships between spectrometer response and the chemical properties of the samples. While many books available on NIR cover a range of applications and topics from a broad perspective, most of them barely touch on structure correlation and interpretation of spectra. The first, and arguably the only, book to tackle this intriguing and challenging area,Practical Guide to Interpretive Near-Infrared Spectroscopypresents the most detailed discussion of the subject to date.
