This author's second volume introduces basic principles of interpreting infrared spectral data, teaching its readers to make sense of the data coming from an infrared spectrometer. Contents include spectra and diagnostic bands for the more common functional groups as well as chapters on polyester spectra and interpretation aids.Discussions include: Science of infrared interpretationLight and molecular vibrationsHow and why molecules absorb infrared radiationPeak heights, intensities, and widthsHydrocarbons, carbonyl groups, and molecules with C-N bondsPolymers and inorganic moleculesThe use of atlases, library searching, spectral subtraction, and the Internet in augmenting interpretation Each chapter presents an introduction to the nomenclature and structure of a specific functional group and proceeds with the important diagnostic bands for each group. Infrared Spectral Interpretation serves both novices and experienced practitioners in this field.The author maintains a website and blog with supplemental material. His training course schedule is also available online.
