Near infrared absorption by SH<sup>-</sup> in alkali halides
<p>The near infrared absorption spectrum of SH<sup>-</sup> in KCl, KBr, KI, RbCl, RbBr, and RbI has been measured over a range of temperatures extending from room temperature down to 1.1° K. The dependence of the absorption spectra on an externally applied electric field was also measured at liquid …

Near infrared absorption bands of the hydroxyl ion in alkali halide crystals
The near infrared absorption bands due to OH- in NaC1, NaBr, KCI, KBr, KI, and RbC1 have been measured at temperatures ranging from 1.4~ to 380 oK. Energy levels of the hydroxyl dipole in the crystal lattice were determined from the spectra. The crystals were grown by the Czochra1ski m~thod in a …

Intrinsic Spectroscopic Tumor Markers Revealed by Double-Differential Analysis of Near-Infrared Absorption Spectra
"Near infrared (NIR) optical methods provide contrast based on quantitative functional changes in tissue. NIR techniques have shown to be sensitive to changes in breast physiology from disease by quantifying total hemoglobin (oxyhemoglobin and deoxyhemoglobin), oxygen saturation, fat content, and …

A spectroscopic system for near infrared glucose measurement
… of complications. In this thesis, the use of the near infrared absorption spectroscopy is proposed and investigated. The light radiation is envisioned to be transmitted through thin tissue such as the webbing tissue between the thumb and the index finger. The main technical difficulties are …

Study of inorganic transparent materials with near-infrared absorbing properties
… in order to find promising candidates for near-infrared absorbers. The chemical systems were chosen due to their absorbing properties and also their chemical and thermal stability and non-toxicity as well as for economical reasons. Investigations were undertaken on several phosphates and …
