Noncooled near-infrared spectroscopy [PDF]
SPIE Proceedings, 1998 We investigate the use of non-cryogenic instrumentation for near IR spectroscopy. With this technique, it is possible to apply in the J and H bands some instrument concepts and observing techniques used in the visible. We present observations of the thermal background in H. We derive some instrument requirements for minimizing and handling it.

Evidence that large vessels do affect near infrared spectroscopy
Scientific Reports, 2022 The influence of large vessels on near infrared spectroscopy (NIRS) measurement is generally considered negligible. Aim of this study is to test the hypothesis that changes in the vessel size, by varying the amount of absorbed NIR light, could profoundly

Near-infrared spectroscopy of autunites
Spectrochimica 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.
