Excerpt from Investigations of Infra-Red Spectra: Part I. Infra-Red Absorption Spectra; Part II. Infra-Red Emission Spectra The free vibration periods Of molecular aggregations may be studied by means Of their emission or absorption spectra. Emission generally implies a high temperature and uncertainty Of the composition Of the radiator, due to dissociation; hence it is more advantageous to study a substance at a low temperature by means Of its absorption spectrum, since we then have a more definite knowledge Of its composition. This is especially true Of the highly complex compounds which are so abun dant in organic chemistry. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.

Interpretive spectroscopy provides a basis for the establishment of cause-and-effect relationships between NIR spectrometer response and the chemical properties of the samples. Without established cause-effect relationships, the measured data has no true predictive significance. This interpretive process is key for achieving an analytical understanding of the measurement. In the expanded second edition of Practical Guide and Spectral Atlas for Interpretive Near-Infrared Spectroscopy, the authors include new research, editorials, supplements, and molecular structural formulas, along with updated references and information on NIR spectra. The thoroughly updated and revised second edition offers a full library of color spectra in a larger format to ensure clarity and reader comprehension. Providing a rich set of reference information required to interpret NIR spectra for research and industrial applications, this book: 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
