Infrared spectroscopy of retinoids
Analytical Biochemistry, 1983The Fourier transform infrared spectra of 15 purified retinoids were compared. Retinoids with conjugated C = O groups revealed the presence of a band between 1730 and 1630 cm-1 X A characteristic of retinoids is the presence of a band between 1650 and 1620 cm-1 due to C = C stretching where three to four conjugated C = O and C = C bonds were present or

European Journal of Pediatrics, 1995
Near infrared spectroscopy is a novel technique still at an early stage in its development. Current technology has been used to measure cerebral haemodynamics and oxygenation at the cotside in sick preterm infants, to observe cerebral oxygenation during birth, and in other situations such as cardiac surgery. At present it is best regarded as a research

Near-infrared spectroscopy is a new technique for noninvasive monitoring of tissue oxygenation and hemodynamics. Until now, it has been used solely for research into the physiopathology of the brain. This technique offers considerable untapped potential for research and clinical applications.

Procedures for Infrared Spectroscopy
Applied Optics, 1972Three procedures are described: a modified Pfund triple-pass absorption cell; an improved image slicer; and new achromatic, doublet lenses. Design parameters for prism dispersion for various prism angles-both simple and composite prisms-are displayed by graphs. The relationships of dispersion and transmission are useful in designing prism spectrometers,

INFRARED-SPECTROSCOPY CHECKERS
The Chemical Educator, 1998The classic strategy game of checkers has been modified to help students study the interpretation of infrared spectra. The exercise gives students practice in functional group recognition, allows them to learn from the mistakes of others, and presents the reading of infrared spectra in a fun and exciting way.

Infrared spectroscopy of lipids
Journal of the American Oil Chemists' Society, 1965AbstractDuring the last ten years, considerable advances have been made in the application of infrared spectroscopy to the study of lipids. This work reviews this contribution.Starting with a brief discussion of the basis of the technique, applications of a qualitative and quantitative kind are described.

Infrared Spectroscopy of Micas
Reviews in Mineralogy and Geochemistry, 2002Infrared (IR) spectroscopy can provide information about details of the atomic structure, lattice dynamics and the chemistry of mineral phases that may not be readily obtained from other analytical techniques. IR spectra originate in transitions between vibrational energy levels of vibrating atomic groups and they are observed as absorption spectra ...
