Near-Infrared Spectrophotometry

Applied Spectroscopy Reviews, 1968
Abstract Near-infrared spectroscopy is usually considered to cover that part of the electromagnetic spectrum which falls between 0.71μ. and approximately 3 p. From the theoretical viewpoint, one might place the upper wavelength limit near 2.51μ. and define near-infrared spectroscopy as the study of low-energy electronic transitions and overtones and ...

Near-Infrared Spectrophotometry

1993
Light absorption in tissue is very limited in the near-infrared range; thus brain tissue may be transilluminated effectively using standard technology. Measurements of brain oxygenation and circulation can be obtained at the cotside. Although the techniques are still under development and the application in newborn infants is still limited, the use of ...

For infrared spectrophotometry of Jupiter and Saturn

Icarus, 1978
Infrared spectral measurements of Mars, Jupiter, and Saturn were obtained from 100 to 470 kaysers and, by taking Mars as a calibration source, brightness temperatures of Jupiter and Saturn were determined with approximately 5 kayser resolution. Internal luminosities were determined from the data and are reported to be approximately 8 times 10 to the ...

Near Infrared Absorption Spectrophotometry

Applied Spectroscopy, 1952
Interest in several regions of the electromagnetic spectrum has increased greatly since the War under the stimulation of new apparatus for the generation and detection of radiation. Just as the perfection of the magnetron and the klystron has given the spectroscopist relatively powerful sources of ...

Identification of Elastomers by Infrared Spectrophotometry

Rubber Chemistry and Technology, 1963
Abstract The use of infrared spectrophotometry for the identification of elastomers is discussed, after having reviewed the general principles on which spectrophotometry is based and after having considered the principal types of atomic vibration.

Measurement of Cell Thickness in Infrared Spectrophotometry

Applied Optics, 1967
It is shown that the usual expression for measuring the cell thickness d(a) of an empty cell, namely, d(a) = lambda(1)lambda(2)N/2(lambda(2) - lambda(1)), where N is the number of fringes over the wavelength range lambda(1) and lambda(2), may only be applied under particular conditions of cell and wall thickness and spectrophotometer characteristics ...

Quantitative Analysis by Infrared Spectrophotometry

Applied Spectroscopy Reviews, 1970
Abstract To complement some current references [1,2] on quantitative infrared analysis, the following goals have been set for this paper: To assess the recent history of quantitative infrared analysis. To describe and illustrate instrumentation and techniques for measuring infrared absorbance simply but precisely.

Infrared and ultraviolet spectrophotometry in residue evaluations

1964
In order to begin this discussion of infrared and ultraviolet spectrophotometry in residue evaluations, it is important to discuss briefly the broad field of spectrophotometry and to define the various regions of the electromagnetic spectrum of interest.

Near-infrared spectrophotometry of Titan

Icarus, 1975
Several unusual features in the near-IR spectrum of Titan are examined. Observations during four apparitions establish the reality of the S(1) absorption at 8150.7 A, but the existence of the S(O) absorption at 8272.7 A will require further sightings to become definitively established. These two features are particularly important, as they bear on the
