Quantitative Determination of Tenoxicam by Infrared Spectrophotometry
Analytical Letters, 1997Abstract The purpose of this study was the quantitative determination of solid dosage forms containing tenoxicam (TNX) by IR spectrophotometry, using the KBr disc technique. Dehydrocholic acid (DHCA) was used as the internal standard. The specific absorption bands at 1420 cm−1 and 1705 cm−1 were chosen for TNX and DHCA, respectively.

Studies of Cryptococcus Polysaccharides by Infrared Spectrophotometry
Journal of Infectious Diseases, 1959Infrared spectrums of isolated capsular polysaccharides have been used to segregate types within certain groups of encapsulated bacteria. The results of spectral typing of purified pneumococcal polysaccharides (1) and of crude klebsiella polysaccharides (2) have paralleled the results of serological typing.

Near Infrared Absorption Spectrophotometry
Applied Spectroscopy, 1952Interest 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 ...

Quantitative Determination of Fluconazole by Infrared Spectrophotometry
Analytical Letters, 1996Abstract The purpose of the study was the quantitative determination of fluconazole by IR spectrophotometry which was realized by the application of the KBr disc technique. In this study dehydrocholic acid was used as internal standard. The absorption bands at 960 and 675 cm−1 were chosen for fluconazole and 1705 cm−1 for dehydrocholic acid.

Near-Infrared Spectrophotometry
Applied Spectroscopy Reviews, 1968Abstract 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 ...

Identification of Elastomers by Infrared Spectrophotometry
Rubber Chemistry and Technology, 1963Abstract 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. There follows a description of the principal methods of analysis for solution and pyrolysis,

For infrared spectrophotometry of Jupiter and Saturn
Icarus, 1978Infrared 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 ...

Quantitative Analysis by Infrared Spectrophotometry
Applied Spectroscopy Reviews, 1970Abstract 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.
