Journal of Near Infrared Spectroscopy, 1998
Some of the concepts that make a near infrared spectrum understandable are reviewed. The origin of vibrational anharmonicity which determines the occurrence and the spectral properties (frequency, intensity) is discussed. The importance of the effects of the resonances which increase with increasing excitation are mentioned.

Functional near-infrared spectroscopy
IEEE Engineering in Medicine and Biology Magazine, 2006The purpose of the this article is to describe an emerging neuroimaging technology, functional near-infrared spectroscopy (fNIRs), which has several attributes that make it possible to conduct neuroimaging studies of the cortex in clinical offices and under more realistic, ecologically valid parameters.

Cerebral oximetry uses transcranial near-infrared spectroscopy (NIRS) to evaluate changes in cerebral oxygenation noninvasively and continuously. Its operation relies on two basic principles. First, near-infrared light has the capacity to penetrate human tissue, including bone. Second, in these tissues, hemoglobin is the predominant absorbing substance

Near-infrared Spectroscopy in the Brewing Industry
Critical Reviews in Food Science and Nutrition, 2012This article offers an exhaustive description of the use of Near-Infrared (NIR) Spectroscopy in the brewing industry. This technique is widely used for quality control testing of raw materials, intermediates, and finished products, as well as process monitoring during malting and brewing.

Near-Infrared Spectroscopy of Dark Asteroids
Icarus, 1994Near-infrared (J, H and K bands) spectra of nine dark asteroids (chosen among a sample of supposed primitive objects between C and D classes) have been obtained at the Mauna Kea Observatory (Hawaii) with the 2.2-m telescope using KSPEC as spectrograph.

In the near-infrared region the absorption process is associated with the overtone and combination bands of vibrational transitions. This region can be studied with the same equipment that is used for electronic spectra, apart from changing from photocell to photoconductive detectors above 1 µ.
