of 4b showed a broad absorption at 3250-3600 [cm.
1] on PCR models because of its strong intensity in the IR spectrum
, it is not obvious in all models but quartz.
Compound (3) was identified as [beta]-sitosterol by co-TLC and complete superimposable IR spectrum
with that of an authentic sample.
The IR spectrum

The IR spectrum
of the flint insert is presented in Figure 3.
When cool roof coatings were introduced, we had to match their existing colors, but with higher reflectance in the IR spectrum
of the sun's energy.
The energy produced by these vibrational modes varies widely over the IR spectrum
, and this is reflected in the wide variety of spectrometers that have been developed.
In the case of our hypothetical tablet, the IR spectrum
confirms that the oily residue is hydrocarbon oil.
On gold nanoparticles that are 5 nm in diameter, the IR spectrum
changes completely, indicating that as much as 78 percent of the peptide takes up a [beta]-sheet structure.
Concentrating on the latest developments for efficiently cooling detectors that operate in the middle- and long-wavelength IR spectrum
, practitioner Piotrowski and Rogalski (applied physics, Military U, of Technology, Warsaw) describe innovations in the cooling of many types of IR photodetectors with emphasis on HgCdTe alloy based detectors.
It can monitor blend composition, cure level, layer thickness, tensile strength, and any other property that correlates with a material's IR spectrum
