Near-Infrared Spectroscopy [PDF]

open access: yes, 2012
Near infrared spectroscopy (NIRS) is an imaging technique used in both clinical and emergency medicine, as well as in research laboratories to quantify and measure the oxygenation status of human tissue non-invasively. This is done by monitoring in vivo changes of the oxygen saturation of hemoglobin molecules in the body, based on the absorbance of ...

Near-infrared spectroscopy of autunites

open access: yesSpectrochimica Acta Part A: Molecular and Biomolecular Spectroscopy, 2005
NIR spectroscopy has been applied to the study water in the interlayer of the autunite minerals. The spectra of autunites and metaautunites in the first HOH fundamental overtone are different and the spectra of autunites of different origins in the 6000-7500 cm(-1) region are considerably different.
