Near Infrared (NIR) Spectroscopy in the Undergraduate Chemistry Curriculum

Abstract
The power of NIR spectroscopy is best and most often realized in the study of compounds containing O-H, N-H and C-H bonds. For example, the content of protein, moisture, carbohydrates, and lipids in complex samples can be determined with the use of NIR spectroscopy. Although there are more conventional methods used for the analysis of these types of compounds, they are lengthy because they require the extraction of the species of interest before the quantification step. NIR spectroscopy, on the other hand, offers the possibility of noninvasive chemical analysis of complex mixtures without the need for time-consuming extraction steps.
