摘要：Infrared (IR) absorption spectroscopy is a kind of vibrational spektroscopy, IR radiation is absorbed by the molecule’s vibrational motion. Each wavelength is obtained fast and high resolution spectra without requiring individually scanning. Even a small amounts of sample are given result in a short time. As in many branches of science are used in food engineering for such purposes as identification of microbial cells, the structural analysis of macromolecules, qualitative and quantitative analysis of organic materials, structural identifications, determination of stereochemistry structures and purity control.
